WebFeb 25, 2024 · Cardinality matching. With cardinality matching, you find the largest subsample of units that satisfies a given balance (i.e., comparability) threshold. There are two ways to do this: classic cardinality matching and template matching. With classic cardinality matching, you must require that the sizes of the two subsamples are the same.

WebThe use of weighted matching for cardinality matching was introduced by Gabow and Tarjan [4]. Their cardinality matching algorithm uses a relaxation of the linear program duals that is helpful for scaling. Our algorithm is based on the standard LP duals. In that respect it differs from [4] at the structural level.
