⚠️There's a newer version (4.5.5) of this package.Take me there.
MatchIt (version 4.5.3)
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) . (The
'gurobi' package, which is not on CRAN, is optional and comes with
an installation of the Gurobi Optimizer, available at
.)
