Dear Stata listeners,
I want to compare nested negative binomial regression models with
robust standard errors (using -nbreg, robust-). Is it permissable to
compare the pseudo-likelihoods of the nested models with a likelihood
ratio test? Is this test statistic still chi-squared distributed? I
think I have come about something like a pseudo-likelihood ratio test,
but do not find any details in my literature on this question. Thank
you in advance.
Thomas
