论文摘要
电子价值已成为P值的潜在替代品,作为不确定性,重要性和证据的衡量标准。简而言之,电子价值是通过随机变量最多的随机变量来实现的。例子包括投注得分,(点为null)贝叶斯因素,似然比和停止的超级马丁。我们设计了使用电子价值(称为E-BH程序)的假发现率(FDR)控制的本杰米尼 - 霍克格(BH)程序的天然类似物(BH)程序,并将其与p值的标准程序进行了比较。我们的中心结果之一是,与通常的BH程序不同,E-BH程序在所需的水平上控制FDR(无需校正),用于电子价值之间的任何依赖性结构。我们说明,在复杂的依赖性,结构化和选择后假设以及多臂匪徒问题的各种设置中,新过程很方便。此外,BH程序是通过P值和电子价值之间的校准进行E-BH程序的特殊情况。总体而言,E-BH程序是一种新颖,功能强大且通用的工具,可用于依赖性多次测试,这是BH程序互补的,每个程序都是不同应用程序中的适当选择。
E-values have gained attention as potential alternatives to p-values as measures of uncertainty, significance and evidence. In brief, e-values are realized by random variables with expectation at most one under the null; examples include betting scores, (point null) Bayes factors, likelihood ratios and stopped supermartingales. We design a natural analog of the Benjamini-Hochberg (BH) procedure for false discovery rate (FDR) control that utilizes e-values, called the e-BH procedure, and compare it with the standard procedure for p-values. One of our central results is that, unlike the usual BH procedure, the e-BH procedure controls the FDR at the desired level -- with no correction -- for any dependence structure between the e-values. We illustrate that the new procedure is convenient in various settings of complicated dependence, structured and post-selection hypotheses, and multi-armed bandit problems. Moreover, the BH procedure is a special case of the e-BH procedure through calibration between p-values and e-values. Overall, the e-BH procedure is a novel, powerful and general tool for multiple testing under dependence, that is complementary to the BH procedure, each being an appropriate choice in different applications.
