# RSiena 1.6.4

## Changes in RSiena:
### Bug correction
  * For `test_gof`,  
    a bug in the handling of auxiliary functions was fixed.


2026-03-23

# RSiena 1.6.3

## Changes in RSiena:
### New function
  * Auxiliary function `egoAlterCovarComb` for `test_gof`. 
### Effects
  * New effects `outdegMixedPop` and `indegMixedPop`.
  * `endowment`=TRUE for `XWX1`, `XWX2`, and `cl.XWX1`.
### Functionality
  * Option `splitDepvars` for `set_algorithm_saom`.
  * The quasi-Newton Raphson update step at the end of Phase 1 used
    matrix `dinvv`, which is the partially diagonalized version of `dinv`.
    This now uses `dinvv`, unless `splitDepvars`=-1.
  * Column names `inter1` and `inter2` of the result of `effectsDocumentation` 
    changed to `covar1` and `covar2`.
  * Better error message for `set_interaction` in case `shortNames`
    is not a list.
  * In `sienaTest` objects, if the test is one-dimensional, the standard error
    of the linear combination is given as an additional component `sterror`
    and included in `print.sienaTest`. 
  * Mean structural dissimilarity values for balance calculations
    dropped from `write_report` (almost never used, therefore confusing).
  * Several checks for objects being of class 'siena' extended to 
    alternatively being of class 'sienadata'.
  * `newparallel.R' extended by a test using `test_gof`. 
  * `importFrom` used for package `network`.
  * " " and "." changed to "_" in `fromObjectToText` (names for `coef` 
    and `vcov`) and `fromObjectToText` (in `siena_table`). 
### C++ coding
  * `Rf_PrintValue` in `Chain.cpp` dropped 
    (was leftover from earlier debugging). 
  * `Rf_findVar` replaced by `R_getVar` in `siena07models.cpp`
    in view of requirements of `R 4.5.3`; requires at least `R 4.5.0`.
  * Depends on R changed to `(>= 4.5.0)`. 
### Bug correction
  * For `transformScript`, processing of `Multipar.RSiena` added. 
  * For `test_gof`,  
    all arguments are transferred to the call of `sienaGOF`.
  * For `interpret_selection`,  
    all arguments are transferred to the call of `selectionTable`. 
  * For `interpret_influence`,  
    all arguments are transferred to the call of `influenceTable`. 
### Documentation 
  * Manual updated to new function names and use of `autograph` for
    plotting influence and selection tables. 
  * In help file for `set_interaction`, treatment of `shortNames`
    corrected.
  * In help file for `set_effect`, treatment of `covar1` and `covar2`
    corrected.

# RSiena 1.6.2

## Changes in RSiena:
### New function
  * Function `transformScript`.
### Function names for exported functions in R
  * New method `write_report` for `sienadata` objects, 
    replacing `print01Report` (which still is retained).
### Functionality
  * Attribute `EgoAlter` added to `sienaGOF` results,
    which is `TRUE` currently only for `egoAlterCombi` 
    (the purpose is to use it for plotting). 
### Coding
  * `returnDeps` mentioned explicitly as an argument for `siena`
    (and not just as an element of ...). 
  * Some occurrences of deparse(substitute(.)) accompanied by
    a check and subsequent potential stop in case of 
    objects resulting from piping.
  * `sienaAlgorithmCreate` modified for different operation 
    in case it is called from `transformScript`.
  * 'parallel.R' in the `tests` directory is replaced by 'newparallel.R' 
    which uses the new names and no `parallelTesting`. 

2026-01-20

# RSiena 1.6.1

## Changes in RSiena:
### New effects
  * Effects `sameXOutAct`, `diffXOutAct`, `crossXOutAct` also implemented
    for two-mode networks.
  * Parameter values 0 and -1 added for `outAct` and `inPop`. 
### Coding
  * <math.h> replaced by <cmath> in C++ code.

2026-01-04

# RSiena 1.6.0

## Changes in RSiena:
### Function names for exported functions in R
  * Overhaul of naming system, which required many new function and methods.
### Bug correction
  * `checkImpossibleChanges` restricted to networks.
  * `checkZeroChanges` adapted to also cover behavioral variables.
### Functionality
  * Warning if `egoAlterCombi` is used with more than 99 ego-alter values.
### Documentation
  * Chapter 3 was inserted in the manual to explain the new function names.
    Appendix A, "List of Functions in Order of Execution", was dropped
    and the author of this appendix, Paulina Preciado Lopez, was
    accordingly dropped from the list of authors of the manual.
    Greetings, Paulina!}
  * Example of `dyadicCov` for ego-alter combinations dropped,
    as this is already covered by `egoAlterCombi`.

2025-11-03

# RSiena 1.5.7

## Changes in RSiena:
## Effects
  * Completely refactored diffusion rate effects as a child of newly
    constructed abstract class behaviorRateEffect that is used in 
    StatisticCalculator and DependentVariable for calculation of rates, scores
    and statistics. New diffusion rate effects can now be added relatively 
    easily with a new cpp file. Closes #97 .
  * NetworkDependentBehaviorEffects can now also use twopath tables. 
    Also added a two-path-count helper function.  
  * New distance 2 exposure diffusion rate effects `totInExposureDist2`, 
   `totAInExposureDist2`, `anyInExposureDist2`, behavior effects `totPopAlt`,
   `totGroup`, `indegAvGroup`, `indegtotGroup`, `totGwdspFFAlt`, `totGwdspFBAlt_nc`
   and new behavior effects without centering `quad_nc`, 
   `avInAltDist2_nc`, `totInAltDist2_nc`, `avTinaltDist2_nc`, `totAInAltDist2_nc`, 
   `totGwdspFFAlt_nc`, `totGwdspFBAlt_nc`.
 * New effects `avSameXAlt`, `totSameXAlt`, `avSameXInAlt`, `totSameXInalt`,
   `avXRecAlt`, totXRecAlt`, `avSameXRecAlt`, `totSameXRecAlt`,
   `avAltSameX`, `totAltSameX`, `avRecAltSameX`, `totRecAltSameX`.
  * New effects `avInAltAltX`, `totInAltAltX`, `avRecAltAltX`, `totRecAltAltX`, 
    `avAltSameX`, `totAltSameX`, `avInAltSameX`, `totInAltSameX`, 
    `avRecAltSameX`, `totRecAltSameX`.
### Coding
  * Slightly refactored contribution, target and actortarget getter to use
  a unified API for setting up C++ objects.
  * Corrected how static contributions are extracted to actually calculate
    correct contributions for the first potential ministep in each period, 
    using the values at the start of the period to calculate allowed changes and
    effect change statistics. This means that there is no calculation of the 
    first ministep after the last observation wave anymore. This also means that 
    sienaRI does not calculate a RI measure at the last observation moment. 
    Added clarification in and cleaned up the documentation and scripts 
    for `siena07`, `sienaRI`, and `sienaRIDynamics`.
  * Eliminated additional test file for chains and integrated into `parallel.R`
    as far as it seemed necessary.
  * Cleaned up some legacy code related to rate effects.
  * Reprogrammed effects `avXAlt`, `totXAlt`, `avXInAlt`, `totXInalt` 
    for greater efficiency (class `AltersCovariateAverageEffect`).
    Removed class `InAltersCovariateAverageEffect`.
  * Dropped `EpochSimulation::updateParameters`, 
    `DependentVariable::updateBasicRate`, 
    `DependentVariable::updateEffectParameters`. These were not used at all.
  * Dropped algorithm as an argument for function `unpackData` and 
    `getChangeContributions`, and as a consequence also from  
    `getTheActorStatistics` and argument `x` from `actorTargets`.
### Documentation
  * A new subsection was added to `Siena_algorithms` to explain the new 
    construction of diffusion rate effects.

# RSiena 1.5.6

## Changes in RSiena:
### Coding
  * The virtual function `preprocessEgo` now is defined properly for 
    the function classes `NetworkAlterFunction`, 
   `CovariateNetworkAlterFunction`, `DoubleCovariateFunction`, 
   `SameCovariateInTiesFunction`. 
   This was done to correct a bug that appeared for effect `sameXInPop`
   for a two-mode network; perhaps there was a similar bug for `diffXInPop`,
   `sameXOutAct`, `diffXOutAct`, and `sameXVInPop`. 
### Functionality:
  * Auxiliary function `egoAlterCombi` for GoF now omits values 
    where the behavioral variable is `NA`.
  * Various small additions to output of `siena07` for `verbose=TRUE` 
    (`phase1.r` and `phase2.r`). 

# RSiena 1.5.5

## Changes in RSiena:
### Coding
  * The virtual function `preprocessEgo` now is defined properly for 
    the function classes `NetworkAlterFunction`, 
   `CovariateNetworkAlterFunction`, `DoubleCovariateFunction`, 
   `SameCovariateInTiesFunction`. 
   This was done to correct a bug that appeared for effect `sameXInPop`
   for a two-mode network; perhaps there was a similar bug for `diffXInPop`,
   `sameXOutAct`, `diffXOutAct`, and `sameXVInPop`. 
### Functionality:
  * Auxiliary function `egoAlterCombi` for GoF now omits values 
    where the behavioral variable is `NA`.
  * Various small additions to output of `siena07` for `verbose=TRUE` 
    (`phase1.r` and `phase2.r`). 

2025-10-17

# RSiena 1.5.3

### Effects
  * New effects `quad_cc`, `avAlt_cc`, `totAlt_cc`.

2025-09-06

# RSiena 1.5.2

## Changes in RSiena:
### Functionality:
  * `selectionTable` got an attribute `quad` indicating whether the plot
    is a quadratic function.
  * Users can now extract now extract the changeContributions when running
    `siena07` by setting an argument `returnChangeContributions=TRUE`. 
    If used together with `nsub=0` and `prevAns` or modified initial 
    values in the effects object, especially useful for post-estimation,
    e.g. in `sienaRIDynamics`.
  * `sienaRIDynamics` uses siena07 directly now and is reinstated.
### Effects
  * New effects `outActMore_ego`, `outActSqrtMore_ego`, `outMore_ego`,
    `outPopMore`, `outPopSqrtMore`, `outPopThreshold`.
### Coding
  * Use `(any(!gmm))` in  `initializeFRAN` to allow the use of a `prevAns` 
    object with a different estimation method for a multigroup estimation.

2025-07-12

# RSiena 1.5.1

## Changes in RSiena:
### Functionality:
  * `sienaRI` reinstated.
  * Option `prML=2` for maximum likelihood estimation 
    using the `move` proposal step reinstated (`sienaAlgorithmCreate`).
### Effects
  * New effects `divOut_ego`, `divIn_ego`. 
### Coding
  * Imported functions from packages `Matrix`, `lattice`, `parallel`, `MASS`, 
    and `xtable` mentioned specifically in the `Namespace`
    instead of importing these entire packages.


# RSiena 1.5.0

2025-07-05

## New CRAN version

## Changes in RSiena:
### Maintainer
  * Christian Steglich now is maintainer.

# RSiena 1.4.25

2025-07-05

## Changes in RSiena:
### Coding
  * Undid other changes in version 1.4.23 to
    `getTargetsChangeContributions` in `siena07setup.cpp`.

# RSiena 1.4.24

2025-07-04

## Changes in RSiena:
### Effects
  * Error for creating effects in effects group `dyadSecondBipartiteObjective` 
    was corrected in file `effects.r`, 
    so they now are included also for changing dyadic covariates.
    This affected effects `XWX`, `XWX1`, and `XWX2`.
### Coding
  * Function `Chains:printConsecutiveCancelingPairs` deleted from `model\ml`,
    because it was not used and led to a protection error.
  * Undid changes in version 1.4.23 to `getTargetActorStatistics` and 
    `getTargetsChangeContributions` in `siena07setup.cpp`.

# RSiena 1.4.23

2025-05-03

## Changes in RSiena:
### Bug corrections
  * Repaired (hopefully) memory leak in `getTargetActorStatistics` and 
    `getTargetsChangeContributions` in `siena07setup.cpp`. 
  * Repaired (hopefully) memory leak in `move` in `MLSimulation.cpp`. 
  * Repaired memory leak  in `DoubleCovariateCatFunction`. 
### Effects
  * New effects `fromAny`, `sameInXCycle4`. 
  * Effect shortName `cycle4ND` replaced by `cycle4`.
  * Better treatment of missing covariate values in effect `sameXCycle4`. 
  * Internal effect parameter values 3 and 4 for `sameXInPop`,`diffXInPop`,
    `sameXInPopIntn`,  `sameXInActIntn`, `homXOutAct2`. 
  * New C++ class `CatCovariateDependentNetworkEffect` (for `homXOutAct2`). 
  * Added `(#)` to the `effectName` of `from`, `sameXInPop`, `diffXInPop`, 
	`sameXVInPop`, `sameXVInPop2`.
### New functionality
  * In `print.sienaEffects(..., includeShortNames=TRUE)`, the `effectNumber`
    is also printed.
### Coding
  * Class `Covariate` has new variable `covariateN`, which then is transferred
    as `covarN` to `CovariateDependentNetworkEffect` and 
    `DoubleCovariateFunction`. 
### Changes in documentation:
  * Definition of effects `outRateLog`, `inRateLog`, and `recipRateLog`
    corrected in the manual.

# RSiena 1.4.22

2025-02-08

## Changes in RSiena:
### New functionality
  * New auxiliary GOF function `egoAlterCombi`. 
  * Parameter `showAll` added to `plot.sienaGOF`.
### New src functionality
  * New table `IntLogTable` and new generic function`IntLogFunction`. 
### Effects
  * Internal parameter 0 (for log(x)) added for `outActIntn`.
    (It would be trivial to implement this also for the other
    mixed degree effects, but currently there seems no need.)
### Bug correction.
  * In `sienaGOF`,  if the auxiliaryFunction does not always 
    give vectors of the same length, the error message gives properly
    the name of the auxiliaryFunction.

# RSiena 1.4.21

2024-12-18

## Changes in RSiena:
### New functionality
  * New functions `selectionTable` and `influenceTable`, 
    with `print` methods. 
### Effects
  * New effect `altHigherEgoX`.
  * Effect `higher` also implemented for symmetric networks.
  * Used # in name of threshold effects.
### Bug corrections
  * In `siena.table`,  fixed parameter values are not reported as NA,
    but as their fixed values.
### Messages
  * If `includeInteraction` is called with argument `parameter`, 
    an error message appears that this keyword should not be given. 
  * Extension of message in `sienaTimeTest` given in the case of
    collinearities. 
### Help pages
  * Improved explanation of the use of `interaction1` and `interaction2`
    in the help page for `includeInteraction`. 

# RSiena 1.4.20

2024-11-10

## Changes in RSiena:
### Effects
  * New effects `varAlt` and `avSimVarAlt`.
### Bug corrections
  * Interaction effects for continuous behavior now turned off. The R side of
    `includeInteraction` for continuous behavior had been implemented but 
    not the C++ side, so now an error message is given.
### Error messages
  * If `includeInteraction' is called for a continuous behavior effect, an
    error message is given that interaction effects are not yet implemented
    for continuous behavior.
### Coding
  * For the new effects, `lvariance`, the behavior variance over all but the 
    last wave, was included as member data of `BehaviorLongitudinalData` 
    together with the corresponding member functions. 

# RSiena 1.4.19

2024-09-03

## Changes in RSiena:

### Effects
  * New effects `outThreshold` and `outThreshold2`.
  * `outActIntn` is an ego effect (`allEffects.csv`).
### New functionality:
  * Network option 11 = `NETCONTEMP` for use of contemporaneous statistics
    for estimating all evaluation effects of the network variable.
### Bug corrections
  * Error corrected that occurred for estimation by the GMoM if
    some effects are fixed.
  * List of effect names when `thetaBound` is exceeded corrected (`phase2.r`).
### Error messages
  * If `setEffect` is called for an effect with `type=gmm`, an error message
    is given that the function called should be `includeGMoMStatistics`. 

# RSiena 1.4.18

2024-07-31

## Changes in RSiena:

### Effects
  * New gmm effects for co-evolution of multiple networks: 
    `crprod_gmm`, `to_gmm`, `from_gmm`.
### Bug corrections
  * Bug corrected in `sienaGOF` which occurred for models with tested effects
    if `iterations` is less than `sienaFitObject$n3`. 
### Coding
  * The new gmm effects required the extension of the function classes
    `AlterFunction`, `NetworkAlterFunction`, and `MixedNetworkAlterFunction`
    to allow making estimation statistics depend totally on the simulated state.
  * Function `fixUpEffectNames(effects, defaultEffects)`
    moved from `initializeFRAN.r` to `sienaEffects.r`. 

# RSiena 1.4.13

2024-06-06

## Changes in RSiena:

### Effects:
  * New effect `homXOutAct2`.
### Bug corrections: 
  * Function `setEffect` corrected (it did not give the proper internal
    parameters in the `effectName`). 
  * Function `updateSpecification` corrected (it did not work properly
    for including interactions).
### Improved functionality:
  * The handling of internal effect parameters in the columns `effectName`
    and `functionName` of `sienaEffects` objects is improved.
    This was achieved by changes in functions `setEffect` 
    and `includeInteraction`.     
    Effectnames as reproduced by `sienaFit` objects should now contain the
    correct values of internal effect parameters.
  * New parameter `thetaBound` for `siena07`, which has the effect of stopping
    the estimation process if some parameters become too large (which would
    signal divergence). 
  * Display of deviations in `siena07gui` modified so that numbers larger 
    than or equal to 1e5 in absolute value are displayed in exponential format
    (and use only one line in the gui) (function `FormatString` in `siena07.r`).


# RSiena 1.4.12

2024-04-27


## Changes in RSiena:

### Improved coding:
  * All objects created by functions, if not print or summary,
   now have an attribute "version", which is the package version.

  * New RSiena logo inst/rsienalogo-2.png


# RSiena 1.4.11

2024-04-23


## Changes in RSiena:

### Effects:
  * Effect name `outOutDist2AvIntn` changed to `avAlt.2M.tot`.

    `dist2OutInActIntn`, `nDist2ActIntn`, `sharedToU`.
  * Changed sqrt treatment in `outOutDist2ActIntn` and
    `outOutDist2AvIntn` / `avAlt.2M.tot`.
### New functionality:
  * Method `print.sienaEffects` has an extra parameter `includeShortNames`
    to do what the name of this parameter suggests.
  * Improved error message for function `updateSpecification`.

# RSiena 1.4.10

2024-03-25


## Changes in RSiena:

### Effects:
  * Effects `sameXV` and `sameXVInPop` added for symmetric networks, 
    and restricted to integer-valued variables in the range from 0 to 20.
### New functionality:
  * Parameter `silent` (new in version 1.4.8) 
    in `sienaAlgorithmCreate` activated. 
### Improved coding:
  * Actor covariates in `sienaData` have a new attribute `lowIntegers` 
    used for in/excluding effects `sameXVInPop` and `sameXV` in
    `getEffects`. 

# RSiena 1.4.9

2024-03-21


## Changes in RSiena:

### Effects:
  * New effects `crossXOutAct`, `outOutDist2ActIntn`, 
    `outOutDist2AvIntn`, `inPopOutW`.
  * New effect group `doubleCovarNetObjective`.
  * New effects `sameXV` and `sameXVInPop` for bipartite networks.
  * `sameXCycle4` added for one-mode and symmetric networks.
  * `sharedTo` gets default internal effect parameter `p=3`. 
### Improved functionality:
  * Function `updateSpecification` now also updates interaction effects
    and `initialValues`.
### Improved coding:
  * Internal functions `numberIntn`, `numberBehIntn`, `checkVersion` 
    defined in file `initializeFRAN.r`.
  * The `Covariate` class and its descendants (all actor covariates)
    now have functions `min` and `max`. 

# RSiena 1.4.8

2024-02-29


## Changes in RSiena:

### Bug corrections:
  * Correction of memory leak in `siena07setup.ccp` for ML estimation.
### New functionality:
  * New parameter `silent` in `sienaAlgorithmCreate`. 

# RSiena 1.4.7

2024-02-21

## New CRAN version

## Changes in RSiena:

### Bug corrections:
  * Correction (again) of error message in `siena07utilities::Rterminate`.

# RSiena 1.4.6

2024-02-19


## Changes in RSiena:

### New functionality:
  * New parameter `targets` in `siena07`, used to supersede the targets
    calculated from the data (not for use in estimation for regular data sets,
    see the help file for `siena07`).
  * `effectsDocumentation` reports to the console
    the name of the file that was written.
  * `sienaDataCreate` stops with an error message if there is a bipartite
    network before a one-mode network.
  * If the data contains a continuous dependent behavioral variable and
    the algorithm specifies conditional estimation, the estimation stops
    with a clear error message.
### Bug corrections:
  * R_NO_REMAP included, and "\Rf_" prepended to all function names used
    from `Rinternals.h` and `R_ext/Error.h` (in `siena07models.cpp`,
    `siena07utilities.cpp`, `siena07setup.cpp` and `siena07internals.cpp`)
    and various other places
    (in accordance with "Writing R Extensions").
  * Corrected wrong length of `lprobabilityArray` in `MLSimulation.h`,
    and cleaned up a bit.
  * In `MLSimulation.cpp`, various sets of "delete" commands reordered so as
    to be in opposite order of the corresponding "new" commands.
  * Correction of error message in `BehaviorVariable::accumulateDerivatives`
    and in `siena07utilities::Rterminate`.
  * Allow `sienaDataCreate` to work with a single variable defined as
    a dependent network given as a list of sparse matrices.
  * Allow `getEffects` to construct effects of more than one dependent network
    on continuous behavior dependent variables.
  * Added some "drop=FALSE" in `initializeFRAN.r` to guard against
    dimension loss in the construction of sparse matrices.
  * Change check for constant dyadic covariates for sparse matrices (issue #88).
  * Some of the recently added effect groups were missing from
    `effectsDocumentation`. This led to an incomplete listing of the effects.
    They are now included.
### Dropped functionality:
  * `sienaRI` temporarily disabled because of a memory leak.
  * The option `prML=2` temporarily disabled because of a memory leak in the
    `move` proposal distribution (`sienaAlgorithmCreate`).
  * `doMoreUpdates` moved from `maxlike.r` to `maxlikecalc.r`.
    The rest of `maxlike.r` as wel as `maxlikefn.Rd` deleted.
    These were not used anywhere.
### Other changes:
  * List of changes in the code before 2022 moved from `NEWS.md` to `ONEWS_gh`.

# RSiena 1.4.5

2024-02-14

## Changes in RSiena:

### Package

  * Migrated package repository to "stocnet" organisation.

### Bug corrections:
  * Put `#include <Rinternals.h>` as the last of the include commands
    in various `.cpp` files (Tomas Kalibera). 

# RSiena 1.4.2

2023-12-14

## Changes in RSiena:

### Effects:
  * New effects `outXMore`, `outMore3`. 
  * `Interactiontype` of `altLThresholdX` and `altRThresholdX` is dyadic.
  * `Interactiontype` of `degAbsDiffX`, `degPosDiffX`, and `degNegDiffX` 
    is "" (blank). 
  * Corrected effect `outMore`. 
### Improved coding:
  * `bxeffects` initialized to 0 in `ContinuousVariable::accumulateScores`.
  * All private variable declarations in the C++ `*.h` files
    were initialized using braces. 
  * In `mixedTriadCensus`, the check of the condition about the matrix 
    dimensions was split into its two parts.
  * `TruncatedOutdegreeEffect2` dropped from `src/model/effects` 
    (was superfluous).
### New functionality:
  * New parameter `iterations` in `sienaGOF` to allow shorter computations.

# RSiena 1.4.1

2023-11-01

# RSiena 1.4.0

2023-10-31

## Changes in RSiena:

### Changes in meta-data:

  * Superfluous files in `inst` directory omitted.
  * New `CITATION`.
### Small changes in coding:
  * Superfluous "lsimulatedDistance" in `SdeSimulation.h` deleted.

    to string in an error message.

# RSiena 1.3.28

## 
   
2023-10-11

## Changes in RSiena:

### Changed effect:
  * `threshold`, `threshold2`, `threshold3`, `threshold4` changed to 
    work with non-centered parameters (not backward-compatible).
### Improved documentation:
  * Descriptions of effects `altInDist2W` and `totInDist2W` added
    to the manual (the effects had been there since a long time, 
    but not documented). 

# RSiena 1.3.27

## 
   
2023-09-29

## Changes in RSiena:

### Coding:
  * Corrected one line in `siena07models.cpp`, which led to slowness of 
    `siena07` since version 1.3.18.
### New effects:
  * `avInSimDist2`, `totInSimDist2`, `sameEgoDist2`,`sameEgoInDist2`,
    `outMore2`, `divOutEgoIntn`, `divInEgoIntn`, `divOutAltIntn`, 
    `divInAltIntn`.
  * `avTAltDist2` and `totTAltDist2` also implemented for behavior co-evolving
    with symmetric networks.
### Documentation:
  * Some explanation is given in the manual about internal effect parameters
    for interactions created by `includeInteraction`.

# RSiena 1.3.26

## 
   
2023-08-15

## Changes in RSiena:

### Coding:
  * Improved Phase 1 derivative matrix computation for basic SDE parameters.
  * Added continuous behavior to returned simulated data.
### Corrections:
  * Period/groupwise tests in `sienaTimeTest` corrected for the case of 
    non-saturated sets of dummy variables.
  * `plot.sienaTimeTest` for "pairwise=TRUE" changed so that the warning
    is avoided. 
  * `sienaGOF` corrected so that again it can handle auxiliary functions
    referring to more than one `varName` (such as in `mixedTriadCensus`).


# RSiena 1.3.24

## 
   
2023-08-01

## Changes in RSiena:

### Corrections:
  * In `getEffects`, the effects object was given an attribute `version`,
    which was not done correctly in version 1.3.23.
    (This led to always giving a warning if any interaction effects were 
    specified.)
  * Corrections of implementation of acceptance by `sienaGOF` of a list of 
    `sienaFit` objects (was not correct in version 1.3.23). 
### Additional testing:
  * function `includeInteraction` used in "parallel.R" (for testing). 


# RSiena 1.3.23
   
2023-06-29

## Changes in RSiena:

### New effects: 
  * New effects `diffWXClosure`, `sameWWClosure`,  `diffWWClosure`, 
    `diffXWClosure`, `sameXWClosure`, `unequalX`.
  * `JoutMix` made available for bipartite dependent networks.
  * For continuous behavior variables depending on a bipartite dependent 
    network, the effect group `continuousBipartiteObjective` was created,
    with effects `outdeg`, `outdegSqrt`, and `isolateOut`. 
  * `sameXOutAct` and `diffXOutAct` now have a parameter 2 for `sqrt`.
### Corrections:
  * In `initializeFRAN`, the call of `getEffects` now is dependent on 
    the value of attribute "onePeriodSde".
  * The error was corrected that occurred if `useStdInits = TRUE` 
    in `sienaAlgorithmCreate` and the effects object includes 
    interaction effects. 
  * In `sienaDataCreate`, the warning message that there is at least one
    `upOnly` period now is made for each dependent variable instead of 
    only the last.
  * In `getEffects`, the effects object was given an attribute `onePeriodSde`
    and an attribute `version`. 
  * In `initializeFRAN`, the comparison between `effects` and 
    `defaultEffects` now is based on `shortName` instead of `effectName` 
    (`effectName` was changed if there are interaction effects),
    excluding the lines in the effects object for `unspInt` and `behUnspInt`
    to allow effects objects created 
    with non-default values of `nintn` and `behNintn`.
### New functionality:
  * The model for continuous behavior variables seems to work now,
    because of the first correction mentioned above.
  * `sienaGOF` now also accepts a list of `sienaFit` objects.
### Improved coding:
  * Better text for stop in `initializeFRAN` when there is a mismatch
    between effects objects disabling the creation of interaction effects.
  * Warning in `initializeFRAN` if the version of the effects object 
    is not current and the effects object contains interaction effects
    (then it is possible that the interacting effects are chosen incorrectly,
    even though the `effectName` of the interaction seems OK).
  * Better error message in `sienaGOF` if `groupName` or `varName` is incorrect.
  * Use default bandwidth selection in violin plot for `sienaGOF`
    (the use of "nrd" sometimes led to absent plots because of negative bw). 

# RSiena 1.3.22

## 
   
2023-05-11

## Changes in RSiena: 
### Coding:
  * Corrected and cleaned up virtual definitions in `AlterFunction` and its
    descendants, in particular `CovariateNetworkAlterFunction`.
  * Added `const` to virtual specification of `value` in `AlterFunction.h`
    and all of its descendants.
  * Replaced ambiguous call to `std::abs` in `AbsDiffFunction.cpp`. 
### New functionality:
  * For one-mode networks, new model options `DOUBLESTEP25`, `DOUBLESTEP50`,
    `DOUBLESTEP75`, `DOUBLESTEP100`. 
### Corrections:
  * The first item in "Coding" implies correction of several distance-2 network 
	 effects such as `altDist2`, `totDist2` and `altInDist2`.
  * In `sienaAlgorithmCreate`, changed default `prML=2` back to `prML=1`; 
    stop if Maximum Likelihood estimation is attempted for a data set
    containing more than one dependent variable 
    with `prML=2` (implemented in `initializeFRAN.r`). 

# RSiena 1.3.20

## 
   
2023-04-22

## Changes in RSiena:  
### Corrections:
  * `updateSpecification` (in `effectsMethods`) now also updates 
    internal parameter values.
  * In `TriadCensus`, the empty network will not lead to an error
    but be reported with the correct triad census.
  * For `reciAct`, check whether internal parameter ==2 replaced by check 
    whether absolute difference from 2 is less than 0.001.
  * In `phase2.r`, `z$sd` is calculated using `sqrt(pmax(..., 0))` to avoid the
    extremely rare case of a negative calculated variance.
  * In `sienaDataCreate`, handling of structurally determined values 
    in `checkConstraints` corrected (thanks to issue raised by Jos Elkink).
### Improvements of functionality:
  * The keyword `parameter` in `includeInteraction` was dropped because it did
    not have any consequences. The help page for `includeInteraction` now 
    explains how internal effect parameters for user-defined interactions
    are determined.
  * The column `dimnames` of the `Simulations` array returned by `sienaGOF` 
    are set to the names of the elements of the auxiliary function.
  * Standard deviations added to output of `descriptives.sienaGOF`.
  * Improved error message in `initializeFRAN` in the case of mismatch between
    effects objects.
  * Warning in `sienaAlgorithmCreate` if `(maxlike && (!is.null(MaxDegree)))`.
    This is now also mentioned in the help page for `sienaAlgorithmCreate`.
### Documentation:
  * Reference about score-type test added to `Wald.Rd`.
  * In the help page for `sienaDependent`, it is mentioned that if there are 
    one-mode as well as two-mode dependent networks,
    the one-mode networks should come first.

# RSiena 1.3.19

## 
   
2023-02-07

## Changes in RSiena:  
### Coding:
  * `siena07internals.cpp` adapted to be compatible with new clang 16 C++ 
    compiler (thanks to Brian Ripley).
### New effects:
  * New effect `inPop_dya`.
  * Parameter 2 for `sameXInPop` and `diffXInPop`.
### Corrections:
  * Help page for `siena07` corrected with respect to `x$lessMem`.
### Improvements of functionality:
  * `coCovar` and `varCovar` now can handle variables with only one 
    non-missing value, but will stop with an error message 
    if all values are missing.

# RSiena 1.3.18

## 
   
2023-01-29

## Changes in RSiena:  
### Improvements of functionality:
  * Additional step type `move` for MH proposal distribution
    for likelihood estimation (thanks to Charlotte Greenan).
  * Accordingly, parameters changed that are used in `sienaAlgorithmCreate`
   for probabilities of MH steps, now summarized in `prML`; with a new default.
  * List elements `accepts`, `rejects`, `aborts` for `sienaFit` objects
    produced by ML estimation improved/corrected by reorganizing them in C++.
  * List element `ac3` added to `sienaFit` object if `maxlike`.

# RSiena 1.3.17

## 
   
2023-01-06

## Changes in RSiena:  

### Improvements of functionality:
  * `sienaGOF` now accepts simulated auxiliary statistics containing missing
    values. If there are any, this will be reported with a warning
    if `giveNAWarning` is `TRUE`.
  * `sienaDataCreate` now also accepts, as "...", a list of such objects.

# RSiena 1.3.16

    `sameXOutPopIntn`, `sameXInActIntn`, `sameXOutActIntn` restored
    (these had got lost in some way...).
### Updates:
  * All occurrences of `http` in `R` and `Rd` files changed to `https`.
  * `seq_len` used and superfluous `c()` omitted in various R files.

# RSiena 1.3.15

## 
   
2022-11-27

## Changes in RSiena:  

### Corrections:
  * `siena08`: correct p-value `pTsq` for overall test statistic `Tsq`
  * `print.summary.sienaMeta`, `siena07`, `print01Report`: drop RForge revision.
  * Correct "objname" to "projname" in `meta.table` (`siena08.r`).
  * Simplify `LaTeX` output of `meta.table`. 
  * `seq_along` and `seq_len` used in `print01Report`.

### Updates:
  * Changes to comply with new version of `Matrix` package.
  * Replacements in some C++ functions of single & and | operators by && and ||.
### Corrections:  
  * `universalOffset` initialized as 0; it was earlier initialized as
    the maximum real number (`NetworkLongitudinalData.cpp`). 
  * `thetaStore` deleted (was trash in `phase2.r`).
  * Various comparisons for vectors with 0 changed to using `all`
    to avoid warnings (`initializeFRAN.r`).
### Code modifications:
  * `sigmas` and `meansigmas` added to `sienaRI` object.
  * Print of standard deviations in the `sienaRI` object for `printSigma=TRUE` 
    changed to using averages at the variance level.
  * If `returnThetas` in the call of `siena07`, also simulated estimation 
    statistics during Phase 2 (deviations from targets) are returned.
### Effects:
  * Several new effects related to primary setting:
    `nonPCompress`, `primCompress`, `primary`, `primDegAct`,
    `primDegActDiff`, `primDegActDiffSqrt`, `primDegActSqrt`,
    `primDegActLog`, `primDegActInv`.

  * New effects `outAct_ego`, `inAct_ego`,`reciAct_ego`, `toAny`.
  * For effects `to`, `toBack`, `toRecip`, `mixedInXW`, 
    internal effect parameter 3 now specifies truncation of the number of 
    twosteps (change to `MixedTwoStepFunction`). 
### Improvements of documentation:
  * Modified help page for `sienaRI`.
  * Small modifications of help page for `sienaGOF`.

# RSiena 1.3.11

# RSiena 1.3.10

## 
   
2022-04-28

## Changes in RSiena:  

### Corrections:
  * Bug corrected that occurred when several two-mode networks were included
    in the dependent variables, with an order restriction between them.
    (Correction of `HigherFilter` and `DisjointFilter`).

### Effects:
  * New effects `avInAltW`, `avWInAlt`, `totInAltW`, `totWInAlt` 
    (with help from Robert Krause).

# RSiena 1.3.8

## 
   
2022-03-07

## Changes in RSiena:  

### Effects:
  * Changed default internal effect parameter for `simAllNear` to 2 and for
    `simAllFar` to 4.

### Improvements of functionality: 
  * In `sienaTimeTest`, added `warn=FALSE` to `varCovar()` to avoid warnings.
  * Small improvements to help pages for `sienaGroupCreate` and `sienaGOF`.

### Corrections:
  * corrected sienaRI for behavioral variables.
    This required changes in 
    `StatisticCalculator::calculateBehaviorStatistics` and
    `StatisticCalculator::calculateBehaviorGMMStatistics`.
  * dropped exclusion of bipartite for sienaRI (only continuous excluded),
    but only if there are fewer second-mode nodes than actors.
    This required changes in 
    `StatisticCalculator::calculateNetworkEvaluationStatistics`
    and in `siena07internals::getChangeContributionStatistics'.
