st: mfx after xtnbreg and how to compute predicted Y

["Pek-Hooi Soh" <phsoh22@gmail.com>]

Hi, I have a count panel data model with interaction terms where the terms
are mean centered.  

I estimated the full model by xtnbreg and ran mfx.  The marginal effect
table presents the same coefficients and standard errors as the table for
xtnbreg. Is this possible?

If I do get the correct mfx output, how do I compute predicted Y? Do I have
compute y = exp(XB) where B stores marginal effects separately in excel ?


Cheers

Pek
