An Objective Measure of Distributional Estimability as Applied to the Phase-Type Aging Model

open access: yesRisks
The phase-type aging model (PTAM) is a class of Coxian-type Markovian models that can provide a quantitative description of the effects of various aging characteristics.

Modelling Students' Length of Stay at University Using Coxian Phase-type Distributions

open access: yesInternational Journal of Statistics and Probability, 2013
The time that Italian students spend at university is remarkably longer than in other European universities. For this reason, the government has recently introduced new rules for academic courses, in order to reduce the issue of long term students. In addition to this, universities need to address the growing problem of students prematurely leaving ...

Distribution and Moments of the Idle Period and Interarrival Time in the G/M/1 Queueing System

open access: yesIEEE Access
The Idle period is relevant in a wide variety of systems and has been extensively studied in the literature. This paper derives the distribution and moments of the idle period for different interrarrival time distributions in the G/M/1 queueing system ...

On the Non-uniqueness of Representations of Coxian Phase-Type Distributions

open access: yes, 2019
Parameter estimation in Coxian phase-type models can be challenging due to their non-unique representation leading to a multi-modal likelihood. Since each representation corresponds to a different underlying data-generating mechanism, it is of interest to identify those supported by given data (i.e., find all likelihood modes). The standard approach is

How Kirkwood and Probability Distributions Differ: A Coxian Perspective

open access: yes, 2016
Kolmogorov's first axiom of probability is probability takes values between 0 and 1; however, in Cox's derivation of probability having a maximum value of unity is arbitrary since he derives probability as a tool to rank degrees of plausibility. Probability can then be used to make inferences in instances of incomplete information, which is the ...

A new method to construct high-dimensional copulas with Bernoulli and Coxian-2 distributions

open access: yesJournal of Multivariate Analysis
We propose an approach to construct a new family of generalized Farlie-Gumbel-Morgenstern (GFGM) copulas that naturally scales to high dimensions. A GFGM copula can model moderate positive and negative dependence, cover different types of asymmetries, and admits exact expressions for many quantities of interest such as measures of association or risk ...

Lattice path approach for busy period density of M/G/1 queues using C3 Coxian distribution

open access: yesApplied Mathematical Modelling, 2007
This paper introduce a new approach to analysing the queueing process, namely lattice paths (LPs). Starting with the \(M/G/1\) queueing system with \(i_{0}\) customers, the authors analyze a busy period with the LP approach. The general distribution in the \(M/G/1\) queueing system is approximated by 3-phase Cox distribution, \(C_{3}\).
