Equilibrium Distributions of Discrete Phase Type

Classification and properties of acyclic discrete phase-type distributions based on geometric and shifted geometric distributions

Acyclic phase-type distributions form a versatile model, serving as approximations to many probability distributions in various circumstances. They exhibit special properties and characteristics that usually make their applications attractive. Compared to acyclic continuous phase-type (ACPH) distributions, acyclic discrete phase-type (ADPH) distributions and their subclasses (ADPH family) have ...

Parameter Estimation of Discrete Multivariate Phase-Type Distributions

This paper considers parameter estimation of a class of discrete multi-variate phase-type distributions (DMPH). Such discrete phase-type distributions are based on discrete Markov chains with marked transitions introduced by He and Neuts (Stoch Process Appl 74(1):37–52, 1998) and is a generalization of the discrete univariate phase–type distributions. Properties of the DMPHs are presented. An E...

Multivariate Discrete Phase-Type Distributions with Their Applications

A dynamic random environment usually induces statistical dependence among components of a system operating in such an environment thereby making explicit computation of the system performance measures very difficult and possibly even intractable. The multivariate phase-type distribution is a powerful tool for unifying a variety of stochastic models and for constructing new models that yield to ...

Some Results on Equilibrium Distributions

‎The equilibrium distributions have many applications in reliability theory, stochastic orderings and random processes. ‎The purpose of this paper is to introduce the equilibrium distributions and presents some results related to this issue. Some results are based on order statistics. ‎In this paper, ‎the generalized Pareto distributions are also analyzed and some basic relationships between t...
