q-Stieltjes classes for some families of q-distributions

Probability 2019-05-27 v2

Abstract

The Stieltjes classes play a significant role in the moment problem allowing to exhibit explicitly an infinite family of probability densities with the same sequence of moments. In this paper, the notion of qq-moment determinacy/indeterminacy is proposed and some conditions for a distribution to be either qq-moment determinate or indeterminate in terms of its qq-density have been obtained. Also, a qq-analogue of Stieltjes classes is defined for qq-distributions and qq-Stieltjes classes have been constructed for a family of qq-densities of qq-moment indeterminate distributions.
