Below, we describe effect estimation after several methods of matching. We consider four broad types of matching that require their own specific methods for estimation effects: 1) pair matching without replacement, 2) pair matching with replacement, 3) full matching, and 4) stratification. http://www.youtube.com/subscription_center?add_user=wildsc0p MatchIt is an R program, and also works seamlessly with Zelig.

What is set.seed() function in R and why to use it ? : set.seed() function in R is used to reproduce results i.e. it produces the same sample again and again. When we generate randoms numbers without set.seed() function it will produce different samples at different time of execution. let see how to generate stable sample of random numbers with set.seed() function in R with example. set.seed As the goal here is to compare matching, the estimation of the ATT (Step 2 of 2) is consistent across all methods, the only distinction is the matching method (Step 1 of 2). Step 2 of 2, estimating the ATT, will be done utilizing the Zelig function native to the MatchIt Package in R. [51] For example, if we want to exclude the observation pair 4 and 20 and the pair 6 and 55 from being matched, the restrict matrix would be: restrict=rbind(c(4,20,-1),c(6,55,-1)) cluster This can either be an object of the 'cluster' class returned by one of the makeCluster commands in the parallel package or a vector of machine names so that GenMatch can setup the cluster automatically.

The tricky part of this matching exercise is that the survey will, in the end, only sample 25 of the 50 treated municipalities. I don't particularly care which 25 of the 50 are chosen; what I am effectively looking for is the top 25 treatment-control pairs from my sample. Is it possible to do this in MatchIt with a distance measure like Entropy balancing for causal effects: A multivariate reweighting method to produce balanced samples in observational studies.
