Hello Henrique,

I am not an expert at pscore by any means, but I have been using propensity
scores for a current project. I had difficulty with the balancing tests and
found that introducing higher order terms for the variable(s) that did not
balance was the easiest way to correct this problem. I think it was the
Stata documents by the authors of the pscore procedure that suggested trying
a less parsimonious model to fix balancing errors.
