generateTVGraph {MultiObjMatch}

Marginal imbalance vs. exclusion

Description

Plotting function that visualizes the tradeoff between the total variation imbalance on a specified variable and the number of unmatched treated units. This function only works for the 'Basic' version of matching (conducted using distBalMatch).

Usage

generateTVGraph(matchingResult)

Arguments

matchingResult

an object returned by the main matching function distBalMatch

Value

No return value, called for visualization of match result

Examples

## Generate matches 
data("lalonde", package="cobalt")
psCols <- c("age", "educ", "married", "nodegree")
treatVal <- "treat"
responseVal <- "re78"
pairDistVal <- c("age", "married", "educ", "nodegree")
exactVal <- c("educ")
myBalVal <- c("race")
r1s <- c( 0.1, 0.3, 0.5, 0.7, 0.9,1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7)
r2s <- c(0.01)
matchResult <- distBalMatch(df=lalonde, treatCol=treatVal, myBalCol=myBalVal,
rhoExclude =r1s, rhoBalance=r2s,
distList=pairDistVal, exactlist=exactVal,
propensityCols = psCols,ignore = c(responseVal), maxUnMatched = 0.1,
caliperOption=NULL, toleranceOption=1e-1, maxIter=0, rho.max.f = 10)
