Hi all,
 
I'm attempting to use pbalchk to calculate the standardized difference in means, before and after conducting a propensity score stratification analysis. I'm trying to determine the code to run the before and after analysis. Here is an example of what I was thinking:
 
Before:
pbalchk treated female
 
After:
pbalchk treated female, strata(quintile)
 
Is getting the "after" results just a matter of adding strata(quintile) to the code?
 
Any help would be much appreciated.
 
Thanks,
Carrie
