Post Hoc Procedures for Some K-Sample Nonparametric Tests for Scale

Journal of Educational and Behavioral Statistics, 1978, vol. 3, issue 3, 265-282

Abstract: Post hoc multiple comparison procedures useful in assessing differences in population variability are formulated for three nonparametric alternatives to the parametric Bartlett test. The three nonparametric tests are the generalized Puri K-sample extensions of the Siegel-Tukey, Mood, and Klotz tests. Theory surrounding the development of these post hoc procedures is outlined and is based upon the chi-square analog to Scheffé’s theorem. An example illustrating an application of the methodology is presented.
