Dear All,
I am using lmer to fit a glmm model using the PQL approximation.
My data is not a Bernoulli (0/1) but a binomial one. The first thing I
noticed is that the method gives me the approximated covariance matrix for the
random effects but nothing about the residuals. In addition, I have the
following estimation that I do not know what deos it mean:
Estimated scale (compare to 1 ) 75043946.
However, when I use the glmmPQL method to fit this model then the problem
doesn't arise, i.e. I have the estimated covariance matrix for the random
effects as well as the standard deviation of the residuals. I would be very
grateful for any comments and/or explanation.
Thank you in advance,
Bernard
