I could not find a package in R about Treatment Effect Analysis.
So is there a R package about Treatment Effect Analysis?
This means, estimating the average treatment effect, average treatment effect on the treated using different methods, including algorithms such as k-neirestnearest-neighbour matching, caliper-matching and things like that?
I found single packages about k-nearest neighbour matching and matching itself (e.g. matching of FNN), but I could not find a comprehensive package about treatment effect analysis.
