Dimensions of Group-based Phylogenetic Mixtures
Hector Baños, Nathaniel Bushek, Ruth Davidson +6
In this paper we study group-based Markov models of evolution and their mixtures. In the algebreo-geometric setting, group-based phylogenetic tree models correspond to toric variet…
Identifiability of linear compartmental models: the singular locus
Elizabeth Gross, Nicolette Meshkat, Anne Shiu
This work addresses the problem of identifiability, that is, the question of whether parameters can be recovered from data, for linear compartmental models. Using standard differen…
Distinguishing Phylogenetic Networks
Elizabeth Gross, Colby Long
Phylogenetic networks are becoming increasingly popular in phylogenetics since they have the ability to describe a wider range of evolutionary events than their tree counterparts.…
The Multiple Roots Phenomenon in Maximum Likelihood Estimation for Factor Analysis
Elizabeth Gross, Sonja Petrović, Donald Richards +1
Multiple root estimation problems in statistical inference arise in many contexts in the literature. In the context of maximum likelihood estimation, the existence of multiple root…
