As one of the criteria for comparing variabilities among distributions, the sample range has attracted considerable … heterogeneous exponential samples. It is shown that the reversed hazard rate of the sample range is a Schur-convex function of the … function of the sample range is Schur-concave in the parameter vector, thereby extending several results known in the …
