Package: MatchIt
Version: 4.7.2
Title: Nonparametric Preprocessing for Parametric Causal Inference
Description: Selects matched samples of the original treated and
        control groups with similar covariate distributions -- can be
        used to match exactly on covariates, to match on propensity
        scores, or perform a variety of other matching procedures.  The
        package also implements a series of recommendations offered in
        Ho, Imai, King, and Stuart (2007) <DOI:10.1093/pan/mpl013>.
        (The 'gurobi' package, which is not on CRAN, is optional and
        comes with an installation of the Gurobi Optimizer, available
        at <https://www.gurobi.com>.)
