Propensity scores of matched and unmatched samples.
Relaxing games are the treated units and control games are the control units.

Empirical quantile-quantile plot of the covariate.
Depicted are the quantiles of the covariate (ADPPs 2019) for the relaxing and control group before and after matching. Small distances between sample points and the diagonal indicate close similarity.
