Dear Stata users,
I am using coarsened exact matching (cem). How are the weights (cem_weights) produced by the Stata command cem exactly calculated? The documentation here writes that "to compensate for the differential strata sizes, cem also returns weights to be used in subsequent analyses." However, I can't seem to find anywhere the exact formula for calculating the weights. Thank you!
