• Added new function cic2 for change-in-changes with multiple periods and variation in treatment timing. This uses the pte package as a backend, and is not fully tested yet.
• bug fixes to allow critical values for uniform confidence band to be affected by alp argument rather than stuck on alp=0.05
• now pass the significance level through in the results
• added functionality to change significance level in ggqte in for pointwise confidence intervals w/o needing to re-estimate
• Updated maintainer’s contact information
• Improvements/updates to vignettes
• Added first-step quantile regression support for panel.qtet, QDiD, CiC
• Added some checks that inputted data is of correct format, particularly in panel data case
• Now using empirical quantiles in CiC method
• Added code for computing uniform confidence bands
• General improvements to codebase, e.g., combining same code used across methods
• Some bug fixes to CiC method
• Added ddid2 method to compute quantile treatment effects under a Difference in Differences assumption following the procedure of Callaway and Li, 2016.
• Include covariates for all methods using formulas (xformla parameter) instead of passing in names
• Improvements to bootstrapping standard errors
• Some extensions to computing the ATT by itself in
• Preliminary version of multi period ATT moved to package
