A Logical Hierarchical Hidden Semi‐Markov Model for Team Intention Recognition
Discrete Dynamics in Nature and Society, Volume 2015, Issue 1, 2015., 2015 Intention recognition is significant in many applications. In this paper, we focus on team intention recognition, which identifies the intention of each team member and the team working mode. To model the team intention as well as the world state and observation, we propose a Logical Hierarchical Hidden Semi‐Markov Model (LHHSMM), which has advantages ...

On the reliability of a renewable multiple cold standby system
Mathematical Problems in Engineering, Volume 2005, Issue 3, Page 269-273, 2005., 2005 We present a general reliability analysis of a renewable multiple cold standby system attended by a single repairman. Our analysis is based on a refined methodology of queuing theory. The particular case of deterministic failures provides an explicit exact result for the survival function of the duplex system.

Análisis de trayectorias estudiantiles mediante distribuciones de fase discretas acíclicas
Revista Latinoamericana de Estudios EducativosEn este trabajo se analizan las trayectorias estudiantiles mediante mezclas de distribuciones de fase discretas acíclicas. El modelo propuesto combina una distribución de Coxian discreta para estimar las probabilidades de deserción en los semestres ...

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

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

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

How Kirkwood and Probability Distributions Differ: A Coxian Perspective
, 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
Journal of Multivariate AnalysisWe 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 ...
