本文已在数学上证明了u_1=u_2=u_3。于是产生了一个值得讨论的问题。2×k表趋势检验的统计量等于两组差异检验Ridit的统计量的事实说明了什么?二者本来是完全不同的两个概念。笔者提出一个大胆的说法:两种检验实际是一个问题的两种表示法,本来就是一回事!笔者还证明了:当
This article has mathematically proved u_1=u_2=u_3. So there was a question worth discussing. What does the fact that the statistics of the 2×k table trend test equals the statistics of two sets of differential test Ridit accounts for? The two are originally two completely different concepts. The author proposes a bold statement: two kinds of tests are actually two representations of a problem, which is originally the same thing! The author also proved that:
