From sample average treatment effect to population average treatment effect on the treated: combining experimental with observational studies to estimate p... Randomized controlled trials (RCTs) can provide unbiased estimates of sample average treatment effects. However, a common concern is that RCTs ...
Many applications of causal analysis call for assessing, retrospectively, the effect of withholding an action that has in fact been implemented. This counterfactual quantity, sometimes called "effect of treatment on the treated," (ETT) have been used to to evaluate educational programs, critic public...

ATEs on the treated (ATETs) Potential-outcome means (POMs) Control-function estimator Endogeneity Test What's this about? Treatment-effects estimators extract experimental-style causal effects from observational data. Examples of treatment effects include effect of a drug regimen on blood pressure, eff...
