checking for balance using standardize difference

Oluwole — Thu, 13 Sep 2018 11:53:39 GMT

I performed propensity score analysis with 2 matched groups. I am not sure if the groups are well matched.

Standardized difference is a method to assess for balance after matched cohort. Can anyone assist me with this process?

Thank you Reeza. Unfortunately, the sas macro was omitted from this paper.

It says contact the authors, they said no?

Otherwise, if you have the latest version of SAS PROC PSMATCH appears to support this:

Thank you Reeza. I did not get a response from the authors for a while. I came across the sas proc Psmatch. My latest version of sas would not support it.
