calipeRmatching

An R package implementing of the caliper matching estimator of the Average Treatment Effect (ATE) and the Average Treatment Effect on the Treated (ATT) of a binary treatment. These effects are estimated by matching on the

• known or
• estimated parametric propensity score. See KPV23 for details.

This package is a wrapper around the C library caliper_matching.

Installation

From R:

install.packages("remotes")
remotes::install_github("kmmate/calipeRmatching")
