Identifiability of parameters in latent structure models with many observed variables
While hidden class models of various types arise in many statistical applications, it is often
difficult to establish the identifiability of their parameters. Focusing on models in which there is …

Phylogenetic ideals and varieties for the general Markov model
The general Markov model of the evolution of biological sequences along a tree leads to a
parameterization of an algebraic variety. Understanding this variety and the polynomials, …

The identifiability of tree topology for phylogenetic models, including covarion and mixture models
For a model of molecular evolution to be useful for phylogenetic inference, the topology of
evolutionary trees must be identifiable. That is, from a joint distribution the model predicts, it …

Identifying the rooted species tree from the distribution of unrooted gene trees under the coalescent
Gene trees are evolutionary trees representing the ancestry of genes sampled from multiple
populations. Species trees represent populations of individuals—each with many genes—…

[HTML][HTML] NANUQ: a method for inferring species networks from gene trees under the coalescent model
Species networks generalize the notion of species trees to allow for hybridization or other
lateral gene transfer. Under the network multispecies coalescent model, individual gene trees …

Identifiability of two-tree mixtures for group-based models
Phylogenetic data arising on two possibly different tree topologies might be mixed through
several biological mechanisms, including incomplete lineage sorting or horizontal gene …

Identifiability of a Markovian model of molecular evolution with gamma-distributed rates
Inference of evolutionary trees and rates from biological sequences is commonly performed
using continuous-time Markov models of character change. The Markov process evolves …
