propensity score 1:4 matching

[lillymaginta]

Hi All

I have data that have the following variables 

treatment : 1 or 0 

variables: dx, dg, dt, dr , df

Can someone share a code for propensity score 1:4 matching without replacement. 

Thank you

What version of SAS do you have? If you have the latest version or SAS UE you should be able to use PROC PSMATCH

Thank you Reeza for the reply. I have the code for 1:1 PSmatch but I need to do 1:4 match so I was wondering if someone has a code of 1-4
