🤖 AI Summary
This work addresses the challenge of controlling the false discovery rate (FDR) under arbitrary dependence structures while enhancing statistical power in online hypothesis testing. The authors propose an online e-closure principle combined with a donation-based composite e-value method, which strictly guarantees FDR control and significantly outperforms existing online multiple testing procedures based on either p-values or e-values. By integrating e-value theory, closure principles, and efficient algorithmic design, the method enables real-time decision-making with a computational complexity of O(log t). Extensive experiments on both synthetic and real-world data demonstrate that the proposed approach achieves superior FDR control accuracy and higher statistical power compared to current state-of-the-art methods.
📝 Abstract
In many scientific applications, hypotheses are generated and tested continuously in a stream. We develop a framework for improving online multiple testing procedures with false discovery rate (FDR) control under arbitrary dependence. Our approach is two-fold: we construct methods via the online e-closure principle, as well as a novel formulation of online compound e-values that is defined through donations. This yields strict power improvements over state-of-the-art e-value and p-value procedures while retaining FDR control. We further derive algorithms that compute the decision at time $t$ in $O(\log t)$ time, and we demonstrate improved empirical performance on synthetic and real data.
