Hi Jeph,
really interested in your response as am having similar issues to Changwoo. How do you go about using these earlier starting models as starting values for the later more complex models.

You don't mention the number of observations and panels, but these
are at least as critical as the number of covariates and random
coefficients. -xtmelogit- will take a very long time to estimate
4 random coefficients if you do not have very many groups.

You may want to start with 1 random coefficient, and use the results
of that model as starting values for a model with 2 random coeffs,
and so on.

Hi all,
I'm using xtmelogit with 50 covariates including 4 random coefficients. Two days ago I ran it but I have only 'refining start values' on the screen. I don't know if Stata still work or not. If it still work, how much time should i wait for getting the results? Thanks in advance.
