On the q-moment determinacy of probability distributions

Sofiya Ostrovska, Mehmet Turan

Given every absolutely continuous distribution can be described in two different ways: in terms of a probability density function and also in terms of a -density. Corre…

Power Lindley distribution and software metrics

Mohammed Khalleefah, Sofiya Ostrovska, Mehmet Turan

The Lindley distribution and its numerous generalizations are widely used in statistical and engineering practice. Recently, a power transformation of Lindley distribution, called…

Uncorrelatedness sets of discrete uniform distributions via Vandermonde-type determinants

Mehmet Turan, Sofiya Ostrovska, Ahmet Yaşar Özban

Given random variables and having finite moments of all orders, their uncorrelatedness set is defined as the set of all pairs for which and $…

Discrete Stieltjes classes for log-Heine type distributions

Sofiya Ostrovska, Mehmet Turan

The Stieltjes classes play a significant role in the moment problem since they permit to expose an infinite family of probability distributions all having equal moments of all orde…

On the invariant manifolds of the fixed point of a second order nonlinear difference equation

Mehmet Turan

This paper addresses the asymptotic approximations of the stable and unstable manifolds for the saddle fixed point and the 2-periodic solutions of the difference equation $x_{n+1}…

q-Stieltjes classes for some families of q-distributions

Sofiya Ostrovska, Mehmet Turan

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…
