I am looking for the way how to match three groups using propensity score matching.
There are three groups, and I want to match via 1:1:1, or 2:1:1
Could you please help for that?
Any kinds of resource or code will be great help for me!
Check this SAS Global Forum paper and see if it helps:
It includes plenty of how-to advice around PROC LOGISTIC.
