Doubly Robust Estimator, In this article, we describe a new Stata command, drglm, that implements the This article proposes doubly robust estimators for the average treatment effect on the treated (ATT) in difference-in-differences (DID) research designs. drtmle implements While doubly-robust estimators facilitate inference when all relevant regression functions are consistently estimated, the same cannot be said when at least one estimator is inconsistent. The approach Doubly robust estimators combine the above two adjustments in a fortuitous way that the causal estimator can be consistent if either the outcome model or the treatment model is correctly specified Thus doubly robust estimators give the analyst two chances instead of only one to make valid infer-ence. This post is heavily inspired by Matheus Facure’s Causal Inference for the Brave and True. It utilizes two models, one for We will show how—even if you misspecify one of the models—you can still get correct estimates using doubly robust estimators. This post is heavily inspired by Matheus Facure’s In the second step, we focus on a doubly robust estimator of the finite population mean and re-estimate the nuisance model parameters by minimizing the asymptotic squared bias of the doubly robust A double-robust estimator gives the analyst two opportunities for ob-taining unbiased inference when adjusting for selection effects such as confounding by allowing for different forms of model This article proposes doubly robust estimators for the average treatment effect on the treated (ATT) in difference-in-differences (DID) research desig 1 Agenda Introduction to importance sampling which is a key concept in reinforcement learning (RL). , the propensity score) to estimate the causal effect of an exposure on an outcome. 2: Simulation 2, estimators for Ŝdiff,strat(u) at selected time points when there is subsample to collect additional covariates.
