Use matchit() to implement a variety of matching procedures including exact matching, nearest neighbor matching, subclassification, optimal matching, genetic matching, and full matching. The output of matchit() can be analyzed via any standard R package, by exporting the data for use in another program, or most simply via Zelig in R.

This estimand is estimable only for methods that allow the ATE and do not discard units from the sample, which in MatchIt is limited to full matching and subclassification when setting estimand This function accepts a MatchIt object (i.e., the result of matchit function) , and calculates standardized mean differences before and after matching.

2018-04-25 · In this brief article, we demonstrate how to get started with matching methods using R and the MatchIt package. To begin we need to load some data. For demonstration purposes we’ll use a sample of the 2015 BRFSS survey (pronounced bur-fiss). BRFSS stands for Behavioral Risk Factor Surveillance System.

Introduction 1.1. What MatchIt does MatchIt implements the suggestions ofHo, Imai, King, and Stuart(2007) for improving parametric statistical models and reducing model dependence by preprocessing data with In this post I borrow from some of the previous references, and try to follow closely the dialogue in chapter 3 of MHE. So, conveniently the R matchit propensity score matching package comes with a subset of the Lalonde data set referenced in MHE. Based on descriptives, it looks like this data matches columns (1) and (4) in table 3.3.2. I have created a Matched Cohort using MatchIt package in R. I have the list of members who are in the treatment group and the control group. But I am unable to figure out which treatment subject is matched to which control group.
