Subject: comparing models with quasipoisson family
Hi,
I am using 'lmer' to fit generalized linear mixed-effects models. I
was just wondering how I can compare two models with identical
fixed-effect terms but different random effects specifications when I
am using the 'quasipoisson' family.
Can I still use 'anova' to compare them? Should a model with
'quasipoisson' family specification produce a logLik value or AIC?
How about the estimate of dispersion parameter as we can get by 'glm'?
Thanks,
Reza
