> m.out <- matchit(treat ~ re74 + re75 + age + educ, data = lalonde, method = "optimal", ratio = 2) where n is a seed number which is an integer value.. The seed number (n) you choose is the starting point used in the generation of a sequence of random numbers.Which is why you’ll obtain the same results given the same seed number. Example of set.seed function in R: generate numeric samples without set.seed() will result in multiple outputs when we run multiple times Estimating Treatment Effects and Standard Errors After Matching. 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.
