Discrete Gompertz-G Family of Distributions for Over- and Under-Dispersed Data with Properties, Estimation, and Applications

Mathematics, 2020
Alizadeh et al. introduced a flexible family of distributions, in the so-called Gompertz-G family. In this article, a discrete analogue of the Gompertz-G family is proposed.

Discrete Analogue of Fishburn’s Fractional-Order Stochastic Dominance

Axioms, 2023
A stochastic dominance (SD) relation can be defined by two different perspectives: One from the view of distributions, and the other one from the view of expected utilities.

Some Functionals and Approximation Operators Associated with a Family of Discrete Probability Distributions

Mathematics, 2023
A certain discrete probability distribution was considered in [“A discrete probability distribution and some applications”, Mediterr. J. Math., 2023]. Its basic properties were investigated and some applications were presented.

A New Method for Generating Discrete Analogues of Continuous Distributions

Journal of Statistical Theory and Applications (JSTA), 2018
In this paper we use discrete fractional calculus for showing the existence of delta and nabla discrete distributions and then apply time scales for definition of delta and nabla discrete gamma distributions.

On a Parametrization of Partial-Sums Discrete Probability Distributions

Mathematics, 2022
For every discrete probability distribution, there is one and only one partial summation which leaves the distribution unchanged. This invariance property is reconsidered for distributions with one parameter. We show that if we change the parameter value

On the Discretization of Continuous Probability Distributions Using a Probabilistic Rounding Mechanism

Mathematics, 2021
Most existing flexible count distributions allow only approximate inference when used in a regression context. This work proposes a new framework to provide an exact and flexible alternative for modeling and simulating count data with various types of ...

Bayesian Estimation in Delta and Nabla Discrete Fractional Weibull Distributions

Journal of Probability and Statistics, 2016
We use discrete fractional calculus for showing the existence of delta and nabla discrete distributions and then apply time scales for definitions of delta and nabla discrete fractional Weibull distributions. Also, we study the Bayesian estimation of the
