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'.
