Geometry of rational quasi-independence models as toric fiber products
Jane Ivy Coons, Heather A. Harrington, Niharika Chakrabarty Paul
We investigate the geometry of a family of log-linear statistical models called quasi-independence models. The toric fiber product is useful for understanding the geometry of param…
Maximum Likelihood Degrees of Brownian Motion Tree Models: Star Trees and Root Invariance
Jane Ivy Coons, Shelby Cox, Aida Maraj +1
A Brownian motion tree (BMT) model is a Gaussian model whose associated set of covariance matrices is linearly constrained according to common ancestry in a phylogenetic tree. We s…
Mixtures of Discrete Decomposable Graphical Models
Yulia Alexandr, Jane Ivy Coons, Nils Sturma
We study mixtures of decomposable graphical models, focusing on their ideals and dimensions. For mixtures of clique stars, we characterize the ideals in terms of ideals of mixtures…
