Tuning is by the\nweighted absolute mean difference balance criterion. The\nresulting score is designed to be supplied directly to the\nmatchit() function of 'MatchIt' as a distance measure, to the\nweightit() function of 'WeightIt' as a propensity score, or to\nthe psave() function of 'psAve' as an appended candidate.", "VignetteBuilder": "knitr", "Config/testthat/edition": "3", "License": "GPL (>= 2)", "URL":
