Generalized Additive Models for Location Scale and Shape R package gamlss version 5.5-0 CRAN Task View: Econometrics (https://CRAN.R-project.org/view=Econometrics) CRAN Task View: MixedModels (https://CRAN.R-project.org/view=MixedModels) Functions for fitting the Generalized Additive Models for Location Scale and Shape introduced by Rigby and Stasinopoulos (2005), <doi:10.1111/j.1467-9876.2005.00510.x>. The models use a distributional regression approach where all the parameters of the conditional distribution of the response variable are modelled using explanatory variables.
