st: Murphy-Topel correction for MLogit - Tobit is possible?

[Sezgin Ayabakan <ayabakan@utdallas.edu>]

Dear Stata community,

I have been using Murphy-Topel correction for a logit (first eq.) - tobit (second eq.) model and I've referred to the paper by Hole (2006), Stata Journal 6 (4). 

However, now I have a categorical variable (3 different cases), so in order to handle this situation I included two binary variables in the tobit model. And these two binary variables are determined within in the system (through exogenous variables and some other variables-instruments). At this point, I'm not sure if I can apply Murphy Topel correction approach. I thought of using mlogit in the first equation, and then getting the predicted probabilities for cases 2 and 3, and using these predicted probabilities in the tobit model. Would mlogit-tobit be possible?

This is my first posting, so hopefully everything is clear.

Thank you,
