Let $X_i$ denote the covariate vector for unit $i$, and suppose Assumption(1) currently requires $X_i$ to be uniformly bounded. Covariate-tail relaxation conjecture. It should be p…

Let $\nu^{\mathsf{rd}}$, $\nu^{\mathsf{rd}\dag}$, and $\mathsf{var}(\widehat{\tau}_{\mathsf{unadj}})$ denote the variance quantities defined in the paper for the covariate-adjusted…

The Fisher randomization test (FRT) is used to analyze experimental data under a specified randomization scheme. An efficient, covariate-adjusted estimator of the average treatment…
