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
.)
