Optimal Designs with Robust Inference for Binary Treatment Effects
David Azriel, Abba M. Krieger, Adam Kapelner
We study randomized experiments with binary outcomes under Neyman's nonparametric model, where covariate measurements are fixed but potential outcomes are random. In this setting w…
Block Designs that Provide Optimal Power in the Cochran-Mantel-Haenszel Test
David Azriel, Adam Kapelner, Abba M. Krieger
We consider the asymptotic power performance under local alternatives of the Cochran-Mantel-Haenszel test. Our setting is non-traditional: we investigate randomized experiments tha…
The Optimality of Blocking Designs in Equally and Unequally Allocated Randomized Experiments with General Response
David Azriel, Abba M. Krieger, Adam Kapelner
We consider the performance of the difference-in-means estimator in a two-arm randomized experiment under common experimental endpoints such as continuous (regression), incidence,…
The Pairwise Matching Design is Optimal under Extreme Noise and Assignments
David Azriel, Abba M. Krieger, Adam Kapelner
We consider the general performance of the difference-in-means estimator in an equally-allocated two-arm randomized experiment under common experimental endpoints such as continuou…
