Re: st: RE: Hurdle, etc programs up

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: 

Marginal effects after ml
     y  = Linear prediction (predict)
        = 14.935113

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

Thanks
