Computing the Distribution of a Tree Metric
David Bryant, Mike Steel
The Robinson-Foulds (RF) distance is by far the most widely used measure of dissimilarity between trees. Although the distribution of these distances has been investigated for twen…
Hadamard Phylogenetic Methods and the n-taxon process
David Bryant
The Hadamard transform of \cite{Hendy89a, Hendy89} provides a way to work with stochastic models for sequence evolution without having to deal with the complications of tree space…
Properties of Consensus Methods for Inferring Species Trees from Gene Trees
James H. Degnan
Consensus methods provide a useful strategy for combining information from a collection of gene trees. An important application of consensus methods is to combine gene trees to est…
Continuous and Tractable models for the Variation of Evolutionary Rates
Thomas Lepage, Stephan Lawi, Paul Tupper +1
We propose a continuous model for evolutionary rate variation across sites and over the tree and derive exact transition probabilities under this model. Changes in rate are modelle…
