SCCD                    Constructs an SCCD for a specified number of
                        runs (n=2m). The construction method is
                        selected automatically according to the number
                        of runs.
conferenceMatrix        Constructs a conference matrix of a specified
                        order using a direct construction for order 2
                        and Paley-based constructions for supported odd
                        prime or prime-power values of q = n - 1.
dOptimalTwoLevel        Constructs a D-optimal two-level design with
                        'm' runs and 'm - 1' factors. The factor levels
                        are coded as -1 and +1.
hadamardMatrix          Constructs a Hadamard matrix of order 'n' using
                        'pracma::hadamard()'.
mixed_level_design      Constructs an orthogonal design for two types
                        of factors with different numbers of levels.
                        Three construction cases are considered:
                        even-even level factors, odd-even level factors
                        and odd-odd level factors. The appropriate
                        construction is selected automatically
                        according to the parity of the numbers of
                        levels of the two factors. Hadamard matrices
                        are used for even-level factors, while
                        conference matrices are used for odd-level
                        factors. The order of both the Hadamard and
                        conference matrices is 'm'. For the even-even
                        case, the design contains 'm - 1' factors of
                        each type. For the odd-even case, the design
                        contains 'm' odd-level factors and 'm - 1'
                        even-level factors. For the odd-odd case, the
                        design contains 'm' factors of each type.
pseudoConference        Constructs a pseudo-conference matrix of order
                        'n' using a determinant-based search procedure.
simulation              Performs a simulation study to evaluate the
                        ability of a design to identify active main
                        effects using best-subsets regression and the
                        AICc criterion.
