you can get the matched data only if you select the row of your data set for which
m$w>0
where m is the output of cem(), i.e.
m <- cem(treatment, data, ecc)
if you use a linear model lm() or similar commands which accept weights, you can pass m$w
as the argument to weights= in your command, i.e. model <- lm( outcome ~ .,
data=mydata, weights=m$w)
you can also use CEM via matchit()

Dear members of the CEM list,
I was wondering if there is a way to extract the data after you match them with CEM? Is
there an equivalent command like match.data in matchit() for CEM?
Best regards,
Ashkan
