This version adds several new functionalities:
- Multiple treatment or control groups
- Multiple separate comparisons, using various subsets of the treatment and control groups, for which units are chosen in order to balance covariate distributions for all comparisons simultaneously
Several changes to the interface have been made:
z
should generally be a factor instead of a vector as beforetreated
andcontrol
specifications, if needed, should each be a level ofz
- many arguments can be specified for each of the treatment levels
q_s
,max_entry_s
can have a row per treatment levelratio
,max_ratio
can have an entry per treatment level
- inputs for the supplemental comparison have been added across the functions:
q_star_s
,ratio_star
,treated_star
,weight_star
There are several changes to the outputs:
optimize_controls
now has only one version ofeps
,objective
,objective_wo_importances
instead of a raw and regular version. The version now reported is the raw version, not corrected for missingness. If you would like corrected versions, refer to the standardized differences outputted bycheck_balance
insteadgenerate_constraints
now returns only standardized outputs, not centered. The centering now takes place withinoptimize_controls
instead
The first released version.
