二元结局下 Fisher 尖锐零假设的差分隐私检验

研究问题
随机实验的二元结局涉及敏感信息时,如何发布检验统计量或概率值,并在限制个体信息泄露的同时检验人人处理效应为零?
方法与思路
作者对统计量或概率值加入校准噪声,并提出显式建模隐私机制的贝叶斯去噪框架,以及贝叶斯风险最优和频率校准决策规则。
材料陈述的贡献
摘要称提出多种差分隐私检验,并通过理论、模拟及 ADAPTABLE 临床试验应用,展示隐私保证下有效且可解释的因果推断。
阅读关注点
应核对随机化设计、数据邻接关系、隐私预算和噪声机制,以及显著性校准的条件、功效损失与贝叶斯决策的损失函数。
阅读边界
这是 arXiv 预印本,同行评审或期刊接收未核实。摘要未给出具体隐私参数与检验条件,无法判断各方法的有限样本适用范围。

原文摘要

Across many disciplines, causal inference often relies on randomized experiments with binary outcomes. In such experiments, often analysts are interested in testing Fisher's sharp null hypothesis, i.e., the treatment has zero effect on the outcome for every study subject. Sometimes the outcomes are sensitive and must be kept confidential, for example, when they comprise physical or mental health measurements. Releasing test statistics or p-values computed with the confidential outcomes can leak information about the individuals in the study. Those responsible for sharing the analysis results may wish to bound this information leakage, which they can do by ensuring the released outputs satisfy differential privacy. In this article, we develop several differentially private tests of Fisher's sharp null for binary outcomes. Specifically, we consider direct perturbation approaches that inject calibrated noise into test statistics or p-values, as well as a Bayesian denoising framework that explicitly models the privacy mechanism. We further develop decision-making procedures under privacy constraints, including a Bayes risk-optimal rule and a frequentist-calibrated significance test. Through theoretical results, simulation studies, and an application to the ADAPTABLE clinical trial, we demonstrate that our methods can achieve valid and interpretable causal inference while ensuring the differential privacy guarantee.
