Webbcomplex, implementing propensity score matching with SAS® is relatively straightforward. An output data set of each subject's propensity score can be generated with SAS using PROC LOGISTIC. And, a generalized SAS macro can generate optimized N:1 propensity score matching of subjects assigned to different groups using the radius method. WebbEstimating Causal Effects with PROC PSMATCH (1) The PSMATCH either computes propensity scores or reads previously-computed propensity scores It provides various methods for using the scores to allow for valid estimation of treatment effect in a subsequent outcome analysis: Inverse probability of treatment weighting Stratification
