A Nonparametric K-sample Test for Variability Based on Gini’s Mean Difference

Abstract In this study, we utilize Gini’s mean difference (GMD) to develop a nonparametric test for comparing variability across K populations. A jackknife empirical likelihood (JEL) method was applied to develop the test statistic, with a chi-squared distribution of K-1 degrees of freedom. Simulati...
