baltest.collect: Collect Covariate Balance Statistics

In ebal: Entropy Reweighting to Create Balanced Samples

Collect Covariate Balance Statistics

Description

A function that summarizes the covariate balance statistics that are computed by MatchBalance(Matching) in a balance table.

Usage

baltest.collect(matchbal.out, var.names, after = TRUE)

Arguments

matchbal.out	An object from a call to MatchBalance(Matching)
var.names	A vector of covariate names.
after	A logical flag for whether the results from before or after Matching should be summarized. If TRUE baltest.collect summarizes the results from the covariate balance checks that MatchBalance computes in the matched data. If FALSE the results from the balance checks in the unmatched data are used.

Details

See MatchBalance(Matching) for details.

Value

A matrix that contains the covariate balance statistics in tabular format.

Examples

## load(Matching) to run this example
## create toy data: one treatment indicator and three covariates X1-3
#dat <- data.frame(treatment=rbinom(50,size=1,prob=.5),replicate(3,rnorm(50)))
#covarsname <- colnames(dat)[-1]

## run balance checks
#mout <- MatchBalance(treatment~X1+X2+X3,data=dat)

## summarize in balance table
#baltest.collect(matchbal.out=mout,var.names=covarsname,after=FALSE)
