Re: st: Regression Equation in ZINB regression |

Thank you Partho. Thank you all for your patience. I have now understood that I cannot get Stata to do this and I need to reconstruct by inserting my co-efficients into the equation. Fine Now the problem I have is finding a general equation for ZINB in order to reconstruct. Is the general equation for ZINB the same as Poisson? I cannot find anywhere a general equation for ZINB. I could use a general log-linear Poisson type equation but would this be correct? and how do I deal with the inflated part, is this merely a seperate log-linear eqn, or is it incorporated into th general ZINB eqn.
