Hi,
I am doing propensity score matching and use the command psmatch2 in Stata 15.1. Below the table of the probit regression the following note appears:
Note: 0 failures and 7 successes completely determined.
What does that mean and what does it mean for my matching exercise? Do I need to drop covariates?
Best,
Florian
