Hi everyone,

I have a couple of trivial questions.

1. How can I estimate overdispersion in a Poisson GLMMM?

Is #lme4:::sigma(model) ok?

2. I am trying to run a quasipoisson GLMM using the lmer function and the
lme4 library but I get a
warning stating that "glmer cannot deal with quasi error families? Any tip?
because I have seen this done.

Thanks
Alejandro
