st: Question About Margeff with nbreg

I ran an nbreg, using the mean dispersion option, with 2 r.h.s.
variables plus the intercept (no offset variable). I got highly
significant coefficient estimates, but the p-values for the
corresponding margeff estimates (of ave. marginal effects over the
sample) were MUCH higher and the confidence intervals for these
margeff estimates were very large.
What might cause this disparity between the results for the
coefficient estimates and the results for the margeff estimates?
