Hi,

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)?

I have conducted some search, but I didn't find any results. Therefore, 
I would appreciate your answers.

Best,

Hsin-yu Tseng
