随机删失配对数据的组合秩检验

研究问题
面对随机删失的配对观测,如何利用删失与未删失信息构造秩检验,并刻画零假设和局部备择下的分布?
方法与思路
作者分别对删失和未删失观测排序后组合统计量,使用合并样本中的秩之差而非差值的秩,以纳入区组间信息。
材料陈述的贡献
摘要称作者获得新统计量在零假设及相邻位置备择下的渐近分布,并给出针对特定备择的评分和真实数据比较。
阅读关注点
应核对删失与配对依赖的假设、两类秩统计量如何组合,以及所称最优评分对应的位置或尺度备择与比较标准。
阅读边界
仅据版本未注明的 OpenAlex 索引摘要,不能推断刊本变化;摘要未详述删失机制和有限样本性质,数据示例不足以确认普遍优势。

原文摘要

Many authors have dealt with the problem of extending ordinary two-sample rank tests to cases where censoring occurs. Albers and Akritas (1987) proposed simple tests for this purpose, based on the idea of making separate rankings for uncensored and censored observations and subsequently combining the resulting two rank statistics. Similarly, some papers appeared that studied the problem of censoring for the paired-data case rather than the two-sample case. This article indicates how the approach of Albers and Akritas can be adapted to the paired-data case. The tests involved are not based on the ranks of the differences, but the differences of the ranks in the pooled sample. In this way, use is made of interblock information. The asymptotic distribution of the new statistic is obtained under the null hypothesis and contiguous location alternatives. By way of example, Wilcoxon- and Savage-type scores are introduced that are optimal for logistic location and exponential scale alternatives, respectively. The two corresponding tests are applied to some real data, and comparisons are made with the results obtained with competing tests on the same data set.
