Use of Renyi's divergence to test for the equality of the coefficients of variation

A new family of test statistics based on Rényi's divergence is introduced for the hypothesis that the coefficients of variation of k normal populations are equal. A comparative simulation study is carried out concerning the size and power of these test statistics and earlier ones. Finally, two...

Sumario:A new family of test statistics based on Rényi's divergence is introduced for the hypothesis that the coefficients of variation of k normal populations are equal. A comparative simulation study is carried out concerning the size and power of these test statistics and earlier ones. Finally, two members of the new family of tests emerge as the best from the simulation study.
