Hi,
I believe we could extend our upcoming release of our
freely available AD Model Builder negative binomial mixed model
http://otter-rsch.com/admbre/admbre.html
packaqge for R to include your model. Writing the model is
simple, it is the interface with R that is a bit more difficult.
If you contact me privately I will take a look at it.
Cheers,
Dave
