>>Thank you very much for your suggestion. When I try the "noconst"
option, however, there are more variables with missing standard
errors...<<

One thing to be wary of when dropping the constant: Several measures
like pseudo-R^2 become invalid or at least not what you think they are
because the reference model changes. Stata's pretty good about about not
showing things it believes are invalid, but you should know what you are
doing.
