Hello,

A while ago the following question was submitted to the Stata
Listserver, but I wasn't able to find a response. As I have the same
question, I am resubmitting the question in the hopes that somebody
could provide some insights:

>While Stata has -heckman- to perform selection corrections for 
>cross-sectional data, I am wondering whether there are any Stata 
>commands or user-written programs that allows me to perform selection 
>corrections for panel data models.
>
>Specifically, are there any commands or programs based on Jeffrey M.
>Wooldridge's paper entitled "Selection corrections for panel data 
>models under conditional mean independence assumptions" (J. of 
>Econometrics, 1995)?

Many thanks,
Colin
