WebMar 1, 2016 · Propensity score matching estimators (Rosenbaum and Rubin (1983)) are widely used in evaluation research to estimate average treatment effects. In this article, … Webpropensity score matching is the common support assumption (p(X i) < 1), which requires the existence of some comparable control units for each treated unit. When propensity score matching is used, the ATT now can be estimated as ATTEE[[ Y i10 D ii=1, pXp(X i)]− E[ [Y i DpD,(p X i)] (3) Th e strategy then consists of computing the dif-

In the statistical analysis of observational data, propensity score matching (PSM) is a statistical matching technique that attempts to estimate the effect of a treatment, policy, or other intervention by accounting for the covariates that predict receiving the treatment. PSM attempts to reduce the bias due to confounding variables that could be found in an estimate of the treatment effect obtained from simply comparing outcomes among units that received the treatment versus those … WebThis video provides an introduction to propensity score matching, and explains why it is a useful concept for deriving estimates for the average causal effec...
