- Fix for change in t.test with paired data to not use the formula notation.
- Added propensity score weighting.
- Fixed a bug where the balance table wasn't combined correctly if the covariates were not specified in the correct order.
- Update to re-release to CRAN.
- Fixes to pass CRAN check.
- Update for compatibility with the multilevelPSA package.
- Fixed new R CMD CHECK notes and warnings.
- Updated for new version of party package.
- Refactored the function for calculating balance to be shared across all the matching procedures.
- Added a vignette about the impact of matching order.
- Fixed an issue where under certain circumnstances there could be a NA effect estimate. These are removed.
- Added better error checking for when a classification tree with no splits occurs.
- The summary function now includes a weighted pooled estimate. This estimate is weighted using the inverse balance estimates so that bootstrap samples with better balance are weighted more to the estimate than those with worse balance.
- You can now specify how the balance estimates are aggregated. Possible values include mean (the default), q25, q75, median, or max.
- Added getPSAbootMethods and global R option "PSAboot.methods" that will return the default set of functions to use in PSAboot.
- Added a number of parameters to the boxplot function including a tufte style from the ggthemes package.
- Initial version of PSAboot package for bootstrapping propensity score analysis.
