Hi,

I'm running a GLMM on binomial choice data.  The outputs I receive are 
sensible except for the degrees of freedom, which come out much larger than 
expected.  Can anyone advise please?

Exptl design:
Response = Choice
Fixed Factors = Position, Treatment and Sex
Random Factor = ID nested within Treatment and Sex
Covariate = Delay

The model:
glmmPQL(FreeChoice ~ Position * Treatment + Sex + Delay, random = list(~Sex 
+ Treatment|Name), family = binomial)

Thanks, Mark
