I am interested in obtaining the matched sample (observations in the treatment group that are matched with observations in the control group) by teffects nnmatch. I want this sample because I want to run a regression on this sample. So I am not interested in the ATE or ATT estimates of teffects nnmatch, but only the matched sample it uses to produce these estimates. Is there a way to obtain the matched sample of teffects nnmatch?
