An Empirical Comparison of the Z-Variance and Box-Scheffe Tests for Homogeneity of Variance
Levy, Kenneth J.
Psychometrika, 40, 4, 519-24, Dec 75
The Z-variance and Box-Scheffe tests for homogeneity of variance are both relatively simple to perform and readily utilized in complex, multi-factor designs. The Z-variance test is not robust against non-normality; the Box-Scheffe test is robust against non-normality but is not nearly as powerful as the Z-variance test. (Author/BJG)
