Building a Propensity Score Model with SAS/STAT® …
www.sas.comPropensity score matching is an intuitive approach that is often used in estimating causal effects from observational data. However, all claims about valid causal effect estimation require careful consideration, and thus many challenging questions can arise when you use propensity score matching in practice. How to select a propensity score ...

Why Propensity Scores Should Not Be Used for Matching
gking.harvard.eduShould Not Be Used for Matching Gary Kingy Richard Nielsenz November 10, 2018 Abstract We show that propensity score matching (PSM), an enormously popular method of preprocessing data for causal inference, often accomplishes the opposite of its in-tended goal — thus increasing imbalance, inefficiency, model dependence, and bias.
