Phylogenetic network models as graphical models
Seth Sullivant
The paper shows that displayed tree phylogenetic network models can be viewed as submodels of graphical models defined by directed acyclic graphs, and uses this perspective to stud…
Singular Learning Theory for Factor Analysis
Mathias Drton, Elizabeth Gross, Dimitra Kosta +4
Watanabe's singular learning theory provides a framework for asymptotic analysis of Bayesian model selection for statistical models with singularities, where traditional statistica…
Identifiability of Large Phylogenetic Mixtures for Many Phylogenetic Model Structures
Bryson Kagy, Seth Sullivant
Identifiability of phylogenetic models is a necessary condition to ensure that the model parameters can be uniquely determined from data. Mixture models are phylogenetic models whe…
Lattice supported distributions and graphical models
Thomas Kahle, Seth Sullivant
For the distributions of finitely many binary random variables, we study the interaction of restrictions of the supports with conditional independence constraints. We prove a gener…
