On the Asymptotic Inadmissibility of Double Machine Learning Estimators Under Structure-Agnostic Models

Lin Liu, Rajarshi Mukherjee, James M Robins

Structure-agnostic (SA) models introduced by Balakrishnan et al. (2026) aim to reflect the general lack of knowledge of structural assumptions on data-generating laws such as smoot…

Mei Dong, Linbo Wang, Lin Liu +1

We discuss the regression-by-composition framework of Farewell, Daniel, Stensrud and Huitfeldt, highlighting a key consequence of its sequential construction: order dependence. Reo…
