Greedy closest-point matching
WebMay 30, 2024 · 1 Answer. This is because of several defaults in Match (). The first scenario is due to the distance.tolerance and ties arguments to Match (). By default, distance.tolerance is 1e-5, which means any control units within a distance of 1e-5 or less of a treated unit will be considered equally close to the treated unit. WebOptimal Matching The default nearest neighbor matching method in MATCHIT is ``greedy'' matching, where the closest control match for each treated unit is chosen …
