Hi stata-users,

I have been trying to understand psmatch2 but it hasn't been very helpful. I don't quite understand how it works and the many variable it produces. I have also tried using teffects but because the observations are in millions and I don't have access to a multi-score stata software, so it doesn't process the command (ran it for over 12 hours - yes!).

What are my next best options in terms of resources for psmatch2 or other packages for matching?

Many thanks.
