On Some Two-Sample Non-Parametric Tests
若干两样本非参数检验
A family of two-sample non-parametric tests is described, in which only the tails of the distributions are used. Some are presented as tests of dispersion and some as tests of location. Critical values for certain of the tests are given for large samples. The power of the tests is discussed, and fresh results are given for a test of dispersion against rectangular alternatives.
