Dear list members, I want to fit a nonlinear mixed model using the nlme command. My dependent variable takes the form of event counts for different countries over a number of years, and hence I was going to fit a mixed effects negative binomial model. The problem, as far as I can glean from Pinheiro & Bates 2000, is that I need a model that is not normal in the errors. All the models they discuss have linear error structures. Is there a package in the R language that fits a negative binomial mixed effects model?
