#### Estimating the relative order of speciation or coalescence events on a given phylogeny

(University of Canterbury. Mathematics and Statistics., 2006)

The reconstruction of large phylogenetic trees from data that violates clocklike evolution (or as a supertree constructed
from any m input trees) raises a difficult question for biologists–how can one assign relative dates ...

#### Computing the distribution of a tree metric

(University of Canterbury. Mathematics and Statistics, 2009)

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 twenty years, an algorithm that is explicitly ...

#### Difficulties in Testing for Covarion-Like Properties of Sequences under the Confounding Influence of Changing Proportions of Variable Sites

(University of Canterbury. Mathematics and Statistics, 2008)

The covarion (COV)-like properties of sequences are poorly described and their impact on phylogenetic analyses poorly understood. We demonstrate using simulations that, under an evolutionary model where the proportion of ...

#### Fast Computation of Supertrees for Compatible Phylogenies with Nested Taxa

(University of Canterbury. Mathematics and Statistics., 2006)

Typically, supertree methods combine a collection of source trees in which just the leaves are labeled by taxa. In such methods the resulting supertree is also leaf labeled. An underlying assumption in these methods is ...
