Sample Size for the One-Way Layout with One Fixed Factor for Ordered Categorical Data
The aim of the paper is to present sample size determination for the Kruskal-Wallis test. The sample size is determined to test the equality of any of the fixed factors in the model for given risks of the first and second kind and the smallest value of the non-centrality parameter. The method is based on the relative effect between the two extreme distributions and on the maxi-min size for the usual F-test.
