# pathintdid 0.1.0

* Initial CRAN release.
* Ported from the community-contributed Stata package (`pathintdid.ado`,
  `pathintdidplot.ado`, `pathintdidrobust.ado`) to R.
* `pathintdid()`: cumulative causal effect (sigma), path-integrated ATT
  (tau-bar), and conventional static DiD, with cluster-style standard
  errors, t-tests, and confidence intervals.
* `pathintdidplot()`: two-panel base-graphics visualization of the
  treated/counterfactual paths and the running cumulative effect.
* `pathintdidrobust()`: dynamic placebo test for pre-treatment parallel
  trends, grid-density/quadrature-scheme sensitivity check, and
  anticipation-robust bounding estimator.
* Bundled example data set `trainingpanel`.
