The Proportional Hazard Generalized Power Weibull Distribution: Properties, Applications and Regression Model

Kudugu Atiah, Suleman Nasiru & Salifu Katara · Asian Journal of Probability and Statistics · 2022

We introduce the proportional hazard generalized power Weibull (PHGPW) model in which hazard rate function can assume increasing, decreasing, unimodal or (upside bathtub) and constant. Some of its mathematical properties are studied including the power series for the quantile fun...

Existence and Uniqueness of Stationary Probability Vector for Stochastic Matrices using Farkas’ Lemma

Somdeb Lahiri · Asian Journal of Probability and Statistics · 2022

The purpose of this note is to provide a simple proof of existence of stationary probability vectors (fixed points) for stochastic matrices using Farkas’ lemma. This result as well as the uniqueness of stationary probability vectors also holds for a certain subclass of quasi-stoc...

Homogeneity versus Parsimony in Markov Manpower Models: A Hidden Markov Chain Approach

Everestus O. Ossai, Precious N. Ezra, Felix O. Ohanuba & Martin N. Eze · Asian Journal of Probability and Statistics · 2022

We aim at tackling the problem of inadequate specification of a Markov manpower model in this paper, by formulating a procedure for validating the inclusion or non-inclusion of some transition parameters in the model. The mover-stayer principle and its extensions are employed to...

On the Riemann Hypothesis

Pathikrit Basu · Asian Journal of Probability and Statistics · 2022

This paper provides an exact characterisation of the zeroes of the Riemann zeta function. The characterisation is based on a theorem about random vectors, which says that under some conditions, if a vector is always in the convex hull of the conditional expectations corresponding...

Probability Model Based on Zero Truncation of Himanshu Distribution and Their Applications

Abhishek Agarwal & Himanshu Pandey · Asian Journal of Probability and Statistics · 2022

In this paper we have developed a probability model to study the distribution of the number of male migrants from households and patterns of child mortality through zero truncated Himanshu distribution (ZTHD). The parameter of the proposed model is estimated by method of moment a...
