RT journal article T1 Stochastic Comparisons of Some Distances between Random Variables A1 Ortega Jiménez, Patricia A1 Sordo Díaz, Miguel Ángel A1 Suárez Llorens, Alfonso A2 Estadística e Investigación Operativa K1 stochastic order K1 copula K1 distance K1 variability measure K1 premium principle AB The aim of this paper is twofold. First, we show that the expectation of the absolute value of the difference between two copies, not necessarily independent, of a random variable is a measure of its variability in the sense of Bickel and Lehmann (1979). Moreover, if the two copies are negatively dependent through stochastic ordering, this measure is subadditive. The second purpose of this paper is to provide sufficient conditions for comparing several distances between pairs of random variables (with possibly different distribution functions) in terms of various stochastic orderings. Applications in actuarial and financial risk management are given.
