Hello Joe, After using your program for estimating a Hurdle of Poisson with hplogit, I got the results of the Poisson-Logit Hurdle Regression After that I tried to estimate the marginal effects with mfx indicating the eqlist(logit poisson) in order to get the marginal effects of the first and second equations. I am indicating the next:

mfx compute, eqlist(logit poisson) nonlinear nodiscrete
Results are:

This results apparently are just for the logit equation. But what about the second equation Poisson?

Thanks

I have also prepared a "generalized negative binomial with endogenous stratification" program which will also be submitted as soon as I finish a help file for it.
All programs require Stata version 9.1 in order to run. Joe Hilbe
