The additional extension it offers is to create panel data using matched sample in both instances Presuming that this is a sample code: library(MatchIt);library(Matching); data(lalonde) lalonde$Serial.number <- seq.int(nrow(lalonde)) lalonde.formu <- treat~age + educ + black + hisp + married + nodegr + re74 + re75 ### Get matched Data using PSM nearest neighbor m.nn<-matchit(lalonde.formu, data = lalonde, caliper=0.1, method ="nearest") nn.match<-match.data(m.nn) write.csv(nn.match, file ="matched.data.csv") #===== #---Outcome analysis using paired t-test # this command saves the data In this tutorial we’ll analyze the effect of going to Catholic school, as opposed to public school, on student achievement. Because students who attend Catholic school on average are different from students who attend public school, we will use propensity score matching to get more credible causal estimates of Catholic schooling. zelig() accepts matched datasets from the MatchIt package as the data argument. First, using the MatchIt package, we attaching the lalonde example dataset, and run matching: 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.

This is achieved by separating substeps of the path of synthesis into compartments. We use chemical containers (chemtainers) to carry the substances through a sequence of fixed successive compartments.
