A Kruskal-Katona theorem for cubical complexes
… complexes, proved independently by J. B. Kruskal and G. A. Katona, is m<sup>(s/r)</sup>. A proof of the formula for cubical complexes is given in this paper, of which a flawed version appears in a paper by Bernt Lindstrijm. The n-tuples which satisfy the optimaiity conditions for cubical …

Comparative Power Of The Anova, Randomization Anova, And Kruskal-Wallis Test
… ANOVA is superior to rank tests such as the Kruskal-Wallis because ranking data disposes of valuable information. To compare the power of the ANOVA, randomization ANOVA, and the Kruskal-Wallis test, the researcher performed a Monte Carlo analysis on group sizes of n=10 to n=30 and groups of …

A New Nonparametric Procedure for the k-sample Problem
… The most commonly used method is that due to Kruskal and Wallis (1952). The method, commonly called the Kruskal-Wallis test, does not assume that the data come from normal populations, though they must still be continuous, but maintains the requirement that the populations must be identical …
