Extinction Times in Multitype Markov Branching Processes [PDF]

open access: yesJournal of Applied Probability, 2009
In this paper, a distributional approximation to the time to extinction in a subcritical continuous-time Markov branching process is derived. A limit theorem for this distribution is established and the error in the approximation is quantified. The accuracy of the approximation is illustrated in an epidemiological example.

Multitype branching processes observing particles of a given type [PDF]

open access: yesJournal of Applied Probability, 2005
A multitype branching process is presented in the framework of marked trees and its structure is studied by applying the strong branching property. In particular, the Markov property and the expression for the generator are derived for the process whose components are the numbers of particles of each type.

Simulating the Emergence and Survival of Mutations Using a Self Regulating Multitype Branching Processes [PDF]

open access: yesJournal of Probability and Statistics, 2011
It is difficult for an experimenter to study the emergence and survival of mutations, because mutations are rare events so that large experimental population must be maintained to ensure a reasonable chance that a mutation will be observed. In his famous

Critical Multitype Branching Processes with Random Migration

open access: yesStochastics and Quality Control
Abstract The aim of this paper is to introduce a multitype branching process with random migration following the research initiated with the Galton–Watson process with migration introduced in [N. M. Yanev and K. V. Mitov, Controlled branching processes: The case of random migration, C. R. Acad. Bulgare Sci. 33 1980, 4, 473–475]. We focus

Duration of a minor epidemic

open access: yesInfectious Disease Modelling, 2018
Disease outbreaks in stochastic SIR epidemic models are characterized as either minor or major. When ℛ01, they can be minor or major. In 1955, Whittle derived formulas for the probability of a minor or a major epidemic.

The Coalescent Structure Of Uniform And Poisson Samples From Multitype Branching Processes

open access: yes, 2023
International audienceWe introduce a Poissonization method to study the coalescent structure of uniform samples from branching processes. This method relies on the simple observation that a uniform sample of size k taken from a random set with positive ...

Functionals of Critical Multitype Branching Processes

open access: yesThe Annals of Probability, 1974
Let $\mathbf{Z}(t) = (\mathbf{Z}_1(t), \cdots, \mathbf{Z}_k(t)), t \geqq 0$, be a critical $k$-type, continuous time, Markov branching process. It is known that $\mathbf{Z}(t)/t$, conditioned on $\mathbf{Z}(t) \neq 0$, converges in distribution to $\mathbf{v}W$, where $\mathbf{v}$ is a vector determined by the mean matrix of the process, and $W$ is an ...

Stochastic two-group models with transmission dependent on host infectivity or susceptibility

open access: yesJournal of Biological Dynamics, 2019
Stochastic epidemic models with two groups are formulated and applied to emerging and re-emerging infectious diseases. In recent emerging diseases, disease spread has been attributed to superspreaders, highly infectious individuals that infect a large ...

Modeling the within-host dynamics of cholera: bacterial–viral interaction

open access: yesJournal of Biological Dynamics, 2017
Novel deterministic and stochastic models are proposed in this paper for the within-host dynamics of cholera, with a focus on the bacterial–viral interaction.
