Hello,

I am using the R function glmmPQL to fit a logistic GLMM, with weights.
I am finding that I get fairly different parameter estimates in glmmPQL
from fitting the full dataset (with no "weight" statement) and an
equivalent, shorter dataset with the weights statement.  I am using the
weights statement in the 'glmmPQL' function exactly as in the 'glm'
function.  I also tested my dataset in the glm function and successfully
got the correct results using the full (with no weights) and the shorter
dataset (with weights).

Is the weight statement in glmmPQL intended to be applied in a different
way to a dataset than how it is used in the glm function?

Thank-you for your help and any suggestions,

Kerrie
