Description: Implements the Path-Integrated Difference-in-Differences
        ('PI-DiD') framework of Salavi (2026), which treats the
        treatment effect as a trajectory tau(t) = c1(t) - c0(t) and
        integrates the baseline-differenced gap over a post-treatment
        window to obtain a cumulative causal effect and a
        path-integrated average treatment effect on the treated,
        together with cluster-robust standard errors, confidence
        intervals, diagnostic plots, and the pre-treatment
        parallel-trends, grid-density, and anticipation-robustness
        checks of section 5 of the companion paper. This approach
        avoids the endpoint-subtraction bias that arises whenever a
        transitory policy's effect has fully decayed by the evaluation
        date, in which case the conventional static
        difference-in-differences estimate can be zero even though the
        cumulative benefit delivered to treated units was strictly
        positive. Formerly distributed as a Stata package under the
        names 'pidid' and 'pididplot'.
