Hi, I'm new to the forum but had a question I can't seem to figure out. I am using a PSM regression and want to find out the # of observations in the treatment and control group that Stata uses when it implements the command. The command below gives me the overall sample, but how many are in treatment and (WIE=1) or in the control group (WIE=0).
Thanks.
