Genealogical constructions of population models
Representations of population models in terms of countable systems of particles are constructed, in which each particle has a ‘type’, typically recording both spatial position and genetic type, and a level. For finite intensity models, the levels are distributed on [0, λ], whereas in the infinite intensity limit λ→∞, at each time t, the joint distribution of types and levels is conditionally Po...
متن کاملGenealogical structuring of a population.
The study observed population of 484 generation restrictive genealogies collected in four Croatian regions during 1970/71 within "The study of fat and carbohydrate metabolism indicators correlated with the occurrence of diabetes in animal fat and oil consuming population groups". The genealogies were collected on two islands (Brac and Hvar) and in two continental regions (Sinjska Krajina and Sr...
متن کاملInferring population history from genealogical trees.
Inference about population history from DNA sequence data has become increasingly popular. For human populations, questions about whether a population has been expanding and when expansion began are often the focus of attention. For viral populations, questions about the epidemiological history of a virus, e.g., HIV-1 and Hepatitis C, are often of interest. In this paper I address the following...
متن کاملGenetic genealogical models in rare event analysis
We present in this article a genetic type interacting particle systems algorithm and a genealogical model for estimating a class of rare events arising in physics and network analysis. We represent the distribution of a Markov process hitting a rare target in terms of a Feynman–Kac model in path space. We show how these branching particle models described in previous works can be used to estima...
متن کاملLine-of-descent and genealogical processes, and their applications in population genetics models.
A variety of results for genealogical and line-of-descent processes that arise in connection with the theory of some classical selectively neutral population genetics models are reviewed. While some new results and derivations are included, the principle aim is to demonstrate the central importance and simplicity of genealogical Markov chains in this theory. Considerable attention is given to "...
