Description: Beta regression for modeling beta-distributed dependent variables on the open unit interval (0, 1),
  e.g., rates and proportions, see Cribari-Neto and Zeileis (2010) <doi:10.18637/jss.v034.i02>.
  Moreover, extended-support beta regression models can accommodate dependent variables with
  boundary observations at 0 and/or 1, see Kosmidis and Zeileis (2025) <doi:10.1093/jrsssc/qlaf039>.
  For the classical beta regression model, alternative specifications are provided:
  Bias-corrected and bias-reduced estimation, finite mixture models, and recursive partitioning for
  beta regression, see Grün, Kosmidis, and Zeileis (2012) <doi:10.18637/jss.v048.i11>.
