1 The Wilcoxon Rank-Sum Test by Chris Wild, University of Auckland The Wilcoxon rank-sum test is a nonparametric alternative to the twosample t-test which is based solely on the order in which the observations from the two samples fall. We will use the following as a running example. ...
首先,在alevel FurtherMaths这本书上对于Wilcoxon rank-sum test(WSRT)的阐述留下了很多疑惑,没有很好的展现该test的意义,完整的说明该test的原理,我在这里会给出一个对于该test补充的说明。 2.历史和介绍 在1940年代,那时候的统计学家们已经不局限于普通的参数检验了,他们觉得样本元素的值的大小也会导致偏差(bia...

前些时候在写作时碰到了 Wilcoxon 检验,仔细一查,发现这里面居然还包含 2 种不同类型的检测,并且极容易混淆,这 2 种分别方法是Wilcoxon rank-sum test(我翻译为秩和检验)和Wilcoxon signed-rank test(我翻译为符号秩检验)。今天我简单总结一下,对比一下他们的差异。

The Wilcoxon Rank Sumtest, also called the Mann Whitney U Test, is a non-parametric test that is used to compare themediansbetween two populations. In other words, it tests if two samples are likely to be from the same population. It performs a similar function as the two-sample independ...
