WebYou'd like to match each point from db1 with a point from db2 such that the "error" of the matching, e.g. sum of distances, will be minimized. A simple greedy approach for solving this might be to generate an m x n matrix with the distances between each pair of coordinates, and sequentially select the closest match for each point. WebMar 15, 2014 · For each of the latter two algorithms, we examined four different sub-algorithms defined by the order in which treated subjects were selected for matching to an untreated subject: lowest to highest propensity score, highest to lowest propensity score, best match first, and random order. We also examined matching with replacement. WebOptimal Matching The default nearest neighbor matching method in MATCHIT is ``greedy'' matching, where the closest control match for each treated unit is chosen one at a time, without trying to minimize a global distance measure. In contrast, ``optimal'' matching finds the matched samples with the smallest average absolute distance … how to run a beer garden
