比例反向风险的两样本非参数检验

Two-sample nonparametric test for proportional reversed hazards

Ruhul Ali Khan

摘要:

在过去的几十年里,已经进行了一些工作的背景下,比例反向风险率(PRHR)。但是,在文献中没有任何具体的统计方法学的PRHR假设。本文提出了一种基于两个独立样本的双样本非参数检验来验证PRHR假设。基于U统计量的一致性,利用U统计量理论、刀切经验似然法和调整刀切经验似然法,发展了三种统计方法学。已经进行了模拟研究,以评估拟议的测试程序的优点。最后,将该测试应用于脑损伤相关生物标志物背景下的数据和Ducheme肌营养不良症相关数据。

英文摘要:

Several works have been undertaken in the context of proportional reversed hazard rate (PRHR) since last few decades. But any specific statistical methodology for the PRHR hypothesis is absent in the literature. In this paper, a two-sample nonparametric test based on two independent samples is proposed for verifying the PRHR assumption. Based on a consistent U-statistic three statistical methodologies have been developed exploiting U-statistics theory, jackknife empirical likelihood and adjusted jackknife empirical likelihood method. A simulation study has been performed to assess the merit of the proposed test procedures. Finally, the test is applied to a data in the context of brain injury-related biomarkers and a data related to Ducheme muscular dystrophy.
