Comparing the Performance of Approaches for Testing the Homogeneity of Variance Assumption in One-Factor ANOVA Models

This simulation study evaluated the performance of 14 tests for the homogeneity of variance assumption in one-way ANOVA models in terms of Type I error control and statistical power, finding the Ramsey conditional, O’Brien, Brown–Forsythe, Bootstrap Brown-ForsYthe, and Levene with squared deviations tests maintained adequate Type Ierror control.
