weighted Ordered-Probit Adjusted Estimator of ATT, but I have noticed
that the standard errors increase slightly. I would like to know if it
is possible to get the variance-covariance matrix after do the matching.
I really don't know if I have to correct my dataset (or the standard
errors) in some sense after matching and before to use it for other
regressions. What do you think??
I will appreciate if you can help me with this problem.
Thanks,
Monica Ospina
