estimations of a given outcome variable from a pooled baseline and follow up dataset:
Single Diff-in-Diff, Diff-in-Diff accounting for covariates, Kernel Propensity Score
Matching diff-in-diff, and the Quantile Diff-in-Diff. diff is also suitable for
estimating repeated cross sections diff-in-diff (including the kernel option) and the
