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…
Rational partition models under iterative proportional scaling
Jane Ivy Coons, Carlotta Langer, Michael Ruddy
In this work we investigate partition models, the subset of log-linear models for which one can perform the iterative proportional scaling (IPS) algorithm to numerically compute th…
Maximum likelihood degree of the two-dimensional linear Gaussian covariance model
Jane Ivy Coons, Orlando Marigliano, Michael Ruddy
In algebraic statistics, the maximum likelihood degree of a statistical model is the number of complex critical points of its log-likelihood function. A priori knowledge of this nu…
The Cavender-Farris-Neyman Model with a Molecular Clock
Jane Ivy Coons, Seth Sullivant
We give a combinatorial description of the toric ideal of invariants of the Cavender-Farris-Neyman model with a molecular clock (CFN-MC) on a rooted binary phylogenetic tree and pr…
