Abstract
Abstract In this paper, the variability of order statistics from heterogeneous random samples is studied. It is shown that, without any restriction on the parameters , the variability of order statistics from heterogeneous exponential samples is always larger than that from homogeneous exponential samples in the sense of Lorenz ordering. Finally, some applications to reliability analysis and auction theory are pointed out.
