Hello,

while using psmatch2 command for effect estimate with replacement, can you please let me know how to know how many times were control individuals used in the estimation of ATT?

For instance, we can use the following data <http://www.stata-press.com/data/r14/cattaneo2.dta> to estimate the effect of "fbaby" on "bweight" In this case I used the following command using one nearest neighbor matching. In the command, I allowed matching with replacement.

Code:
psmatch2 fbaby fage mmarried mage , outcome(bweight) neighbor(1) logit

So my question, in the area of common support, how do we know that the number of control observations used in minimum and maximum with replacement?
