Dear all

I hope that this message finds you well, and is not too trivial. I am running a negative binomial model with random effects. I tried to estimate the conditional mean using the command “predict mean, nu0” and I had the following message “warning: estimated value of r is less than one; expected value undefined”. What does that mean, please? How can I estimate this conditional mean? Thank you in advance for your reply.
