Greetings, I am interested in using a generalized linear mixed model with data that best fits a beta distribution (i.e., the data is bounded between 0 and 1 but is not binomial). I noticed that the beta distribution is not listed as an option in the "family objects" for glmmPQL or lmer. I found a thread on this listserve from 2006 ("[R] lmer and a response that is a proportion") that indicated that there was no package available for mixed effects models with a beta distribution at that time. This thread also indicated that package betareg did not allow inclusion of random effects.
Does anyone know of a package or code for a generalized linear mixed model that allows a beta distribution? Transforming my data might allow me to use another family, but I would rather not transform the data if possible. Thanks for your help!
