I haven't quite been able to figure out some of the variables psmatch2 produces. I have used
Code:
set seed 1234 generate id=uniform() sort id psmatch2 admit, pscore(pscore) caliper(0.0024762) noreplacement descending common logit
Code:
drop if _weight==.
Any advice?
PS. I am sort of stuck with psmatch2 because no other package can run through such a big dataset in minutes.
For those wondering what the weights look like:
psmatch2: |
weight of |
matched |
controls | Freq. Percent Cum.

5 | 324 0.04 100.00
