Evaluating and Learning Optimal Dynamic Treatment Regimes under Truncation by Death arXiv:2510.07501v1 Announce Type: new Abstract: Truncation by death, a prevalent challenge in critical care, renders traditional dynamic treatment regime (DTR) evaluation inapplicable due to ill-defined potential outcomes. We introduce a principal stratification-based method, focusing on the always-survivor value function. We derive a semiparametrically efficient,…
