关于广义错误发现率

On a generalized false discovery rate

Sanat K. Sarkar, Wenge Guo

摘要:

$k$-FWER的概念最近受到了很多关注,因为对于某些固定的$k\ge 1$,当人们试图至少控制$k$错误拒绝时,它是用于多次测试的适当差错率。一个不太保守的概念,$k$ -FDR,最近由Sarkar [Ann. Statistist. 34(2006)394--415],概括了Benjamini和Hochberg的错误发现率[J. Roy.中央集权主义者Soc.Ser.B57(1995)289- 300]。在这篇文章中,我们带来了新的见解$k$ -FDR考虑一个混合模型,涉及独立的$p$值之前,激发一些新的程序,控制它的发展。我们证明了$k$ -FDR控制的建议方法在一个稍微弱的条件下比在混合模型。我们提供了数值证据,所提出的方法优于某些$k$ -FWER和$k$ -FDR方法的功率性能。最后,我们将我们的方法应用到一个真实的数据集。

英文摘要:

The concept of $k$-FWER has received much attention lately as an appropriate error rate for multiple testing when one seeks to control at least $k$ false rejections, for some fixed $k\ge 1$. A less conservative notion, the $k$-FDR, has been introduced very recently by Sarkar [Ann. Statist. 34 (2006) 394--415], generalizing the false discovery rate of Benjamini and Hochberg [J. Roy. Statist. Soc. Ser. B 57 (1995) 289--300]. In this article, we bring newer insight to the $k$-FDR considering a mixture model involving independent $p$-values before motivating the developments of some new procedures that control it. We prove the $k$-FDR control of the proposed methods under a slightly weaker condition than in the mixture model. We provide numerical evidence of the proposed methods' superior power performance over some $k$-FWER and $k$-FDR methods. Finally, we apply our methods to a real data set.
