Thanks Annees,
the categories seem not to be involved in other critical issues.
Sure, mlogtest, w gives me the test for jointly significance of coefficients.
With all the available mlogtest the problem persists: I have no
categories with no obs, but one of them (or at max 2) has lower sample
size relative to the other. I don't know, my issue might be due by a
combination of both this small relative s.s and also to the
(relatively) high number of categories qhich might cause such a kind
of "confusion in STATA".
