Standardized Mean Differences

pink_poodle — Wed, 27 May 2026 15:47:22 GMT

Hi friends,

I am doing the following:

1. Obtaining propensity scores

2. Converting them to model weights

3. Running the model

The model runs as follows:

PROC SURVEYREG DATA = ps;
	MODEL dyhosp = grp; 
	WEIGHT IPS;
RUN;

I need to compute Standardized Mean Differences (SMDs) as the fourth step. Please advise.

Many thanks,

Eva

Standardized mean differences can be computed in PROC PSMATCH which performs propensity scoring. See the Getting Started example in the PSMATCH documentation.

You could calculate Cohen's d statistic to get a standardized mean difference.
