The result is that _nn only has a value for approximately 10% of the observations. Stata does not have a built-in command for propensity score matching, a non-experimental method of sampling that produces a control group whose distribution of covariates is similar to that of the treated group.

After running -diff- you can use -psgraph- which is a post estimation command of -psmatch2- and you will get a graph like the following:Hi everybody, I'm new to the STATA reddit.
