A Comparison of Some K-Sample Nonparametric Tests for Scale.
Penfield, Douglas A.; Koffler, Stephen L.
Four nonparametric alternatives to the parametric Bartlett test are presented for handling the K-sample equality of variance problem. The two sample Siegel-Tukey Test, Mood Coefficient of Alienation Test, and Klotz Test are extended to the multisample situation by the methods of Puri. A fourth alternative involving a Q-statistic procedure developed by Chatterjee is also presented. These K-sample scale tests are illustrated and compared with respect to computational methodology and asymptotic relative efficiency for specified alternatives. (Author)
