support.sas.comThe propensity score would then be the predicted probability of receiving the treatment. Propensity scores are being used in observational studies to reduce bias. Three commonly used techniques are subclassification on the propensity score, regression adjustment using the propensity score, and case-control matching on the propensity score.
Why Propensity Scores Should Not Be Used for Matching
gking.harvard.eduRubin,1984), and some uses of the propensity score within other methods (e.g. Diamond and Sekhon,2012; Imai and Ratkovic,2014). Moreover, the mathematical theorems in the literature used to justify propensity scores in general, such as in Paul R. Rosenbaum and Rubin (1983), are of course correct and useful elsewhere, but we show they are not
