Abstract: diff performs several differences in differences (diff-in-diff) estimations of the treatment effect of a given outcome variable from a pooled base line and follow up dataset: Single Diff-in-Diff, Diff-in-Diff controlling for covariates, Kernel-based Propensity Score Matching diff-in-diff, and the Quantile Diff-in-Diff. diff is also suitable for estimating repeated cross section diff-in-diff (except for the kernel option).
