contdid 0.1.2 (2026-10-30)
- Bug fix:
cont_did() with target_parameter = "level" and
aggregation = "eventstudy" passed the continuous dose, rather than a
treated/comparison indicator, to the underlying DiD estimator. This
made the estimator weight treated units by their dose and put weight
on some treated units in the comparison group, so event-study ATT
estimates from earlier versions were biased when treatment effects
are nonzero. With DRDID >= 1.4.0, which now requires a binary
treatment indicator, this case failed with an error instead. Other
combinations of target_parameter and aggregation were not
affected.
contdid 0.1.1 (2026-07-21)
- Resubmission to CRAN following archival on 2026-07-16 (contdid was
archived because its dependency
ptetools had been archived;
ptetools has since been restored to CRAN as version 1.0.1).
- Require
ptetools (>= 1.0.1) in Imports to prevent recurrence.
- Update
ggcont_did() to use ptetools's autoplot() methods in
place of the now-deprecated ggpte()/ggpte_cont().
contdid 0.1.0 (2025-07-03)
- Initial CRAN submission.
- CCK estimation is working for case with two periods.
- Change default parametric specification to cubic polynomial.
- Bug fix for variable names.
contdid 0.0.002
- Added sanity checks for unexpected input data.
