WebJul 9, 2024 · Matching. Compute a distance between the propensity score for each treated subject with every control. Then use the nearest neighbor (i.e., greedy mathcing) or optimal matching as before. In practice, logit (log-odds) of the propensity score is often used, rather than the propensity score itself. WebThere are basically two types of matching algorithms. One is an optimal match algorithm and the other is a greedy match algorithm. A greedy algorithm is frequently used to match cases to controls in observational studies. In a greedy algorithm, a set of X Cases is matched to a set of Y Controls in a set of X decisions.
