Could you please verify that the code below is properly constructed?
nearest0 <- matchit(treat ~ age+lunch+iep+gender+cogat+mapfall+itbs, data = Run0031,
method="nearest", exact=c("lunch","iep"))
nearest1 <- matchit(treat ~ age+lunch+iep+gender+cogat+mapfall+itbs, data = Run0031,
method="nearest", caliper=0.1)
opt <- matchit(treat ~ age+lunch+iep+gender+cogat+mapfall+itbs, data = Run0031,
method="optimal", ratio=1)
This the segment of my code for doing PSM on one run of my data using 3 different
methods.
Thanks!
