WebThe goal of this article is to construct doubly robust (DR) estimators in ignorable missing data and causal inference models. In a missing data model, an estimator is DR if it remains consistent when either (but not necessarily both) a model for the missingness mechanism or a model for the distribution of the complete data is correctly specified.

WebAn estimator for this common parameter vector is called Doubly Robust (DR) if it™s consistent no matter which model is correct. We provide a general technique for constructing DR estimators (assuming the models are over identi–ed).
