Beyond R0: demographic models for variability of lifetime reproductive output. [PDF]

open access: yesPLoS ONE, 2011
The net reproductive rate R0 measures the expected lifetime reproductive output of an individual, and plays an important role in demography, ecology, evolution, and epidemiology.

ClickClust: An R Package for Model-Based Clustering of Categorical Sequences

open access: yesJournal of Statistical Software, 2016
The R package ClickClust is a new piece of software devoted to finite mixture modeling and model-based clustering of categorical sequences. As a special kind of time series, categorical sequences, also known as categorical time series, exhibit a time ...

Quantum Markov Chains: A unification approach [PDF]

open access: yesarXiv, 2018
In the present paper we study a unified approach for Quantum Markov Chains. A new quantum Markov property that generalizes the old one, is discussed. We introduce Markov states and chains on general local algebras, possessing a generic algebraic property, including both Boson and Fermi algebras.

Positive recurrence and transience of a two-station network with server states [PDF]

open access: yesarXiv, 2013
We study positive recurrence and transience of a two-station network in which the behavior of the server in each station is governed by a Markov chain with a finite number of server states; this service process can represent various service disciplines such as a non-preemptive priority service and K-limited service.

Elementary Bounds On Mixing Times for Decomposable Markov Chains [PDF]

open access: yesarXiv, 2015
Many finite-state reversible Markov chains can be naturally decomposed into "projection" and "restriction" chains. In this paper we provide bounds on the total variation mixing times of the original chain in terms of the mixing properties of these related chains. This paper is in the tradition of existing bounds on Poincare and log-Sobolev constants of

Exact analysis of summary statistics for continuous-time discrete-state Markov processes on networks using graph-automorphism lumping

open access: yesApplied Network Science, 2019
We propose a unified framework to represent a wide range of continuous-time discrete-state Markov processes on networks, and show how many network dynamics models in the literature can be represented in this unified framework.

Building mean field ODE models using the generalized linear chain trick & Markov chain theory

open access: yesJournal of Biological Dynamics, 2021
The well known linear chain trick (LCT) allows modellers to derive mean field ODEs that assume gamma (Erlang) distributed passage times, by transitioning individuals sequentially through a chain of sub-states.
