Hello.

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!

Thank you.

Check this SAS Global Forum paper and see if it helps:

 

A General SAS® Macro to Implement Optimal N:1 Propensity Score Matching Within a Maximum Radius

 

It includes plenty of how-to advice around PROC LOGISTIC.

Also, check out PROC PSMATCH (new in SAS 9.4 TS1M4) which can do propensity score matching.
