On the sample ranges from heterogeneous exponential variables

Xu, Maochao; Balakrishnan, N. - In: Journal of Multivariate Analysis 109 (2012) C, pp. 1-9

In this paper, the sample range from a heterogeneous exponential sample is shown to be larger than that from a homogeneous exponential sample in the sense of the star ordering. Then, by using this result, some equivalent characterizations of stochastic comparisons of sample ranges with respect...

A characterization of the distribution function: the dispersion function

Muñoz-Perez, J.; Sanchez-Gomez, A. - In: Statistics & Probability Letters 10 (1990) 3, pp. 235-239

The dispersion function, defined as D(u) = E | X - u |, characterizes the distribution function and gives a dispersive … ordering of probability distributions that presents interesting properties. …
