Some tests of whether several samples are from identical populations
Authors:Lionel Weiss
Institution:Cornell University
Abstract:We observe s Independent samples, from unknown continuous distributions. The problem is to test the hypothesis that all the distributions are identical. The distribution of the numbers of observations from s-1 of the samples which fall in cells whose Boundaries are selected order statistics of the remaining sample, the number of cells increasing gradually with the sample sizes, is investigated. It is shown that under the null hypothesis and nearDy alternatives, as the sample sizes Increase these numbers of observations can be considered to be slightly rounded off normal random variables, the amount rounded off decreasing as sample sizes increase. Using these results, various tests of the hypothesis can be constructed and analyzed.
Keywords:nonparametric inference  order statistics  asymptotic distribution theory
