Beta Regression CRAN Task View: Econometrics (http://CRAN.R-project.org/view=Econometrics) CRAN Task View: Psychometrics (http://CRAN.R-project.org/view=Psychometrics) Beta regression for modeling beta-distributed dependent variables, e.g., rates and proportions. In addition to maximum likelihood regression (for both mean and precision of a beta-distributed response), bias-corrected and bias-reduced estimation as well as finite mixture models and recursive partitioning for beta regressions are provided.
