[R-sig-ME] over-dispersed Poisson with lmer -- a trick, with a catch?

[dave fournier]

Hi,

Instead of "tricks", why don't you just fit a negative binomial mixed
model. That should deal with the over-dispersion. You can do this with
AD Model Builder's random effects package which is now freely available
at http://admb-project.org.
