Dear Statalist,

I hope this finds you well. I would like to ask regarding the new version of Stata 16. In fact, I used to work on the Stata version 15 and two weeks ago I made an upgrade for the software but I found that the company has sent to me version 16 instead of 15. My concerns regarding the syntax command in the software: are there big differences between the two versions need to be considered while continuing working on my analysis? Do I need to use (xt) for the regression, such as xtheckman especially that in Stata 15 the command is heckprobitt? I am no familiar with using xt for regression analysis, any advice, please.


Many thanks for your reply and your kind cooperation

Kind regards,
Rabab
