- Note: The above table reports the test of balance of the mean propensity score between the treated and controls by blocks. The results are from implementing “pscore.ado” program in Stata. The P-values are based on a two-sample t-test with equal variance. The pscore command fits a logit (probit is the default) model with a starting specification of linear terms without interactions or higher order terms. If balance in not achieved in a block, the sample in the block is split into equally spaced intervals, with higher order terms and interactions included, and the average propensity score of the treated and controls is re-tested till balance is achieved
