Kehan Wang, Wenxuan Song, Wangli Xu, Linglong Kong

TL;DR
This paper introduces SUP, a novel private multiple testing framework that maintains super uniformity of p-values under privacy constraints, enabling effective inference while controlling Type-I errors.
Contribution
We develop a new p-value transformation, a reversed peeling algorithm, and privacy-parameter-free thresholds, advancing private multiple testing with theoretical guarantees and improved power.
Findings
SUP outperforms existing private methods in power.
The framework effectively controls Type-I errors under privacy.
Simulations and real data validate the approach.
Abstract
Multiple testing is widely applied across scientific fields, particularly in genomic and health data analysis, where protecting sensitive personal information is imperative. However, developing private multiple testing algorithms for super uniform -values remains an open question, as privacy mechanisms introduce intricate dependence among the peeled -values and disrupt their super uniformity, complicating post-selection inference. To address this, we introduce a general Super Uniform Private (SUP) multiple testing framework with three key components. First, we develop a novel \( p \)-value transformation that is compatible with diverse privacy regimes while retaining the super uniformity. Next, a reversed peeling algorithm is designed to reduce privacy budgets while facilitating inference. Then, we provide diverse rejection thresholds that are privacy-parameter-free and tailored…
