Optimal matching for observational studies
WebFeb 6, 2024 · Implements optimal matching with near-fine balance in large observational studies with the use of optimal calipers to get a sparse network. The caliper is optimal in the sense that it is as small as possible such that a matching exists. The main functions in the 'bigmatch' package are optcal() to find the optimal caliper, optconstant() to find the … WebInthispaper, wedevelopanoptimalmatchingmethodformultileveldatastructures. Contrary to intuition, our method first matches pairs of units and then clusters to create matched pairs of clusters with pairs of units within these cluster pairs.
