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.engUse of Renyi's divergence to test for the equality of the coefficients of variationjournal articlehttp://www.sciencedirect.com/science/article/pii/S037704279900312Xhttp://www.sciencedirect.com/open access519.22Coecient of variationRenyi's divergenceSimulationSizePowerEstadística matemática (Matemáticas)1209 Estadística
