I have been trying to fit a beta regression to a percentage/proportion outcome variable. I used libraries as glmmTMB, gamlss, and betareg for that matter. Since I can see some potential outliers in the residual plots, I was wondering if there is a package that can fit robust beta regression models? Thanks in advance. WebMar 1, 2006 · The authors present maximum-likelihood regression models assuming that the dependent variable is conditionally beta distributed rather than Gaussian, and approach models both means and variances with their own distinct sets of predictors, thereby modeling heteroscedasticity.
