I am analysing binomial data using a generalised mixed effects model.  I
understand that if I use glmmPQL it is not appropriate to compare AIC
values to obtain a minimum adequate model.

 

I am assuming that this means it is also inappropriate to use AIC values
from lmer since, when analysing binomial data, lmer also uses PQL
methods.  However, I wasn't sure so please could somebody clarify this
for me.

 

I was also wondering how best to assess your minimum adequate model
without AIC values?  Do you simply have to rely on the p values
associated with the t-values/z-values?

 

Thanks very much.
