The research described herewith is to re-visit the classical doubly robust estimation of average treatment effect by conducting a systematic study on the comparisons, in the sense of asymptotic efficiency, among all possible combinations of the estimated propensity score and outcome regression. To this end, we consider all nine combinations under, respectively, parametric, nonparametric and semiparametric structures. The comparisons provide useful information on when and how to efficiently…

Estimating Conditional Average Treatment Effects

We consider a functional parameter called the conditional average treatment effect (CATE), designed to capture the heterogeneity of a treatment effect across subpopulations when the unconfoundedness

Estimation of Regression Coefficients When Some Regressors are not Always Observed

Abstract In applied problems it is common to specify a model for the conditional mean of a response given a set of regressors. A subset of the regressors may be missing for some study subjects either

Simulation studies show that the doubly robust estimator of the causal effect which was constructed by the authors has better statistical properties in terms of bias and mean squared error (MSE); the values calculated from the asymptotic variance of the proposed estimator and the empirical variance are relatively close.

Doubly robust estimation of causal effects.

The authors present a conceptual overview of doubly robust estimation, a simple worked example, results from a simulation study examining performance of estimated and bootstrapped standard errors, and a discussion of the potential advantages and limitations of this method.

On the Role of the Propensity Score in Efficient Semiparametric Estimation of Average Treatment Effects

The role of propensity score in the efficient estimation of the average treatment effects is examined. If the treatment is ignorable given some observed characteristics, it is shown that the

Rejoinder: Demystifying Double Robustness: A Comparison of Alternative Strategies for Estimating a Population Mean from Incomplete Data

When outcomes are missing for reasons beyond an investigator's control, there are two different ways to adjust a parameter estimate for covariates that may be related both to the outcome and to

Semiparametric double robust and efficient estimation for mean functionals with response missing at random

Semiparametric Estimation and Inference Using Doubly Robust Moment Conditions

We study semiparametric two-step estimators which have the same structure as parametric doubly robust estimators in their second step, but retain a fully nonparametric specification in the first

Assignment to Treatment Group on the Basis of a Covariate

When assignment to treatment group is made solely on the basis of the value of a covariate, X, effort should be concentrated on estimating the conditional expectations of the dependent variable Y

Stratification and weighting via the propensity score in estimation of causal treatment effects: a comparative study

Estimation of treatment effects with causal interpretation from observational data is complicated because exposure to treatment may be confounded with subject characteristics. The propensity score,
