改进的Mann-whitney统计量在趋势检验中的应用

Application of modified Mann-whitney statistics to trend test

利用改进的Mann-whitney统计量,给出了趋势检验问题的一个检验统计量.证明了此统计量是渐近正态的,并利用蒙特卡罗方法对统计量的渐进分布做了统计模拟.

Based on the modified Mann-whitney statistics, a statistics for trend test is given. It is proved that the statistics is asymptotic normality, and simulation of the statistics＇s asymptotic distribution is carried out with Monte Carlo method.
