Entropy balancing using PROC PSMATCH

MadQuant — Tue, 11 Oct 2022 18:38:18 GMT

Hi all,

I am trying out various matching methods to do run regressions. Kudos to the fact that

PROC PSMATCH

was added a few years ago. So I was able to carry out propensity score matching sucessfully.

But I also wanted to try out entropy balancing and found this recently added document. (https://documentation.sas.com/doc/en/pgmsascdc/v_031/statug/statug_psmatch_examples10.htm).

So I followed it.

However, my sas spits out an error message.

proc psmatch data=drugs;
    class Drug Gender;
    eweight treatvar=Drug(Treated='Drug_X') balancevars=(Gender Age BMI) nlargestwgt=5;
    -------
    180
ERROR 180-322: Statement is not valid or it is used out of proper order.

FYI, running PROC PRODUCT_STATUS gives me below. Basically Base SAS version is 9.4M6, SAS/STAT 15.1.

Any help is much appreciated. Thanks.

Insofar as I know, entropy balancing in PROC PSMATCH requires SAS Viya.
