Hello,
I am looking into using CEM in a context where I need to match subsets of
the treatment group separately based on the timing of treatment
(unfortunately, the simple solution of using time as a matching component
won't work in my case).
After matching, I would like to combine the matched subsets to estimate a
pooled treatment effect. Do the cem_weights need to be revised to account
for pooling? If so, is there a reference that describes how the cem_weights
are created? I understand their basic purpose - to account for differential
strata sizes - but I'm not clear on the actual formula that is used to
generate the weights for matched controls.
Thank you,
Zack
