Then, we can install MatchIt via the command (or RStudio -> packages -> Install -> MatchIt). matchit is the main command of the package MatchIt, which enables parametric models for causal inference to work better by selecting well-matched subsets of the original treated and control groups. MatchIt implements the suggestions of Ho, Imai, King, and Stuart (2004) for improving parametric statistical models by preprocessing data with nonparametric matching methods. MatchIt implements a matchit for a detailed explanation of the inputs and outputs of a call to matchit. method_full for optimal full matching, which is similar to subclassification except that the number of subclasses and subclass membership are chosen to optimize the within-subclass distance. Examples matchit.exec(url, match) Returns: Object. Returns an object an object of key:val pairs, as defined by your route pattern.

Its functions conduct several computations that 'MatchIt' does not provide. It takes the 'MatchIt' result object and/or the original data to compute standardized mean differences (SMD) between groups before and after matching. It also calculates ratio of variances and ratio of residual variances.

matchit is the main function of MatchIt and performs pairing, subset selection, and subclassification with the aim of creating treatment and control groups balanced on included covariates. MatchIt implements the suggestions of Ho, Imai, King, and Stuart (2007) for improving parametric statistical models by preprocessing data with nonparametric matching methods. MatchIt provides a simple and straightforward interface to various methods of matching for covariate balance in observational studies. Matching is one way to reduce confounding and model dependence when estimating treatment effects.
