The PSMATCH Procedure - SAS
support.sas.comprovides three strategies for propensity score matching. Greedy nearest neighbor matching selects the control unit nearest to each treated unit. Greedy nearest neighbor matching is done sequentially for treated units and without replacement. Optimal matching selects all control units that match each treated unit by minimizing the total absolute
