两个人口的空间分布之间的差异的统计假设检验。该测试是基于两个单变量概率分布之间的差异的双样本Cramer-von Mises测试的推广。它的目的是敏感的方式在整个研究区域的人口分布的差异，但不敏感的两个人口之间的丰度差异。该程序是非参数的，并使用随机化检验的方法来确定检验统计量的显著性水平。
A statistical hypothesis test for a difference between the spatial distributions of two populations is presented. The test is based upon a generalization of the two—sample Cramer—von Mises test for a difference between two univariate probability distributions. It is designed to be sensitive to differences in the way the populations are distributed across the study area but insensitive to a difference in abundance between the two populations. The procedure is nonparametric and uses the methodology of a randomization test to determine the level of significance of the test statistic.
