Kingman coalescent

Kingmans Koaleszenz ist ein stochastischer Prozess aus der Koaleszenztheorie, einer Theorie, die sich mit stochastischen Prozessen von Partikeln beschäftigt, die mit der Zeit Cluster formen. Solche Prozesse finden Anwendung in der Populationsgenetik, wobei man die Cluster wieder als Partikel interpretiert. Kingmans Koaleszenz hat die besondere Eigenschaft, dass sie in einer Partition von unendlich vielen Partikeln beginnt, sich aber nach jeder positiven Zeit fast sicher en… WebKingmans Koaleszenz ist ein stochastischer Prozess aus der Koaleszenztheorie, einer Theorie, die sich mit stochastischen Prozessen von Partikeln beschäftigt, die mit der Zeit Cluster formen.

Mutations occurring to ancestors in the tree determine the gene types in the sample.

In particular, this shows the weak convergence of \({\mathscr {X}}_t\) in an appropriate time scale, provided the particles are initially spread out. blackstone russia ukraine

WebKingman’s coalescent process is a mathematical model of genealogy in which only pairwise common ancestry may occur. Inter-arrival times between successive … WebKingman’s coalescent process is a mathematical model of ancestral lineages that inspired a paradigmatic era in population genetics [1–3]. Kingman’s coalescent process [4–7] relies on negligibility of coalescence probabilities, and inter-arrival times, other than those of single pair-wise coalescence.

Web2.1. The Kingman coalescent. Kingman developed the coalescent model [25, 23, 24] to study the limit of several finite population size models such as the Wright-Fisher model [14, 45] and the Moran model [33]. This makes it a suitable general model for the genealogy of a sample taken from a population of large size. As explained in [7], while ... WebTajima’s coalescent has a drastically smaller state space, and hence it is a computationally more efficient model, than the standard Kingman coalescent. We provide a new algorithm for efficient and exact likelihood calculations for data without recombination, which exploits a directed acyclic graph and a correspondingly tailored Markov Chain Monte Carlo method.
