Many statistical estimands can expressed as continuous linear functionals of a conditional expectation function. This includes the average treatment effect under unconfoundedness and generalizations for continuous-valued and personalized treatments. In this paper, we discuss a general approach to estimating such quantities: we begin with a simple plug-in estimator based on an estimate of the conditional expectation function, and then correct the plug-in estimator by subtracting a minimax linear estimate of its error. We show that our method is semiparametrically efficient under weak conditions and observe promising performance on both real and simulated data.

  1. Optimal Estimation of Generalized Average Treatment Effects using Kernel Optimal Matching

    stat.ME 2019-08 conditional novelty 6.0 of 10

    Kernel Optimal Matching is extended to estimate any generalized average treatment effect, including a new data-chosen estimand, KOWATE, with worst-case optimal balancing and root-n consistency.
