Multivariate and Propensity Score Matching with Balance Optimization
Provides functions for multivariate and propensity score matching
and for finding optimal balance based on a genetic search algorithm.
A variety of univariate and multivariate metrics to
determine if balance has been obtained are also provided.
Matching: Multivariate and Propensity Score Matching Software for Causal Inference
Jasjeet S. Sekhon
This website is for the distribution of "Matching" which is a R package for estimating causal effects by multivariate and propensity score matching. The package provides functions for multivariate and propensity score matching and for finding optimal balance based on a genetic search algorithm. A variety of univariate and multivariate tests to determine if balance has been obtained are also provided. These tests can also be used to determine if an experiment or quasi-experiment is balanced on baseline covariates.
For an introduction to the package with documentation and examples, please see "Multivariate and Propensity Score Matching Software with Automated Balance Optimization: The Matching package for R." Journal of Statistical Software, 42(7): 1-52. 2011.
How to install
A version is on CRAN. The latest development version can be installed directly from Github using devtools.
if (!require("devtools")) install.packages("devtools") devtools::install_github("JasjeetSekhon/Matching")
The package contains compiled code, and you must have a development
environment to install the development version. (Use
devtools::has_devel() to check whether you do.) If no development
environment exists, Windows users download and install
Rtools and macOS
users download and install
