Abstract

The purpose of this paper is to present some results related to the dispersive ordering of probability distributions via dispersion functions of the -random variables. A new approach to the Laws of Large Numbers in -norm can be applied via received results. A new concept on minimum-dispersive unbiased estimator is considered, too.
