  journal={arXiv: Statistics Theory},
We give an explicit formula for the reciprocal maximum likelihood degree of Brownian motion tree models. To achieve this, we connect them to certain toric (or log-linear) models, and express the Brownian motion tree model of an arbitrary tree as a toric fiber product of star tree models.

Brownian motion tree models are toric
Felsenstein's classical model for Gaussian distributions on a phylogenetic tree is shown to be a toric variety in the space of concentration matrices, and it is demonstrated how the toric structure leads to exact methods for maximum likelihood estimation. Expand

The maximum likelihood degree of toric varieties
The maximum likelihood (ML) degree of toric varieties, known as discrete exponential models in statistics, is studied, showing that the ML degree is equal to the degree of the toric variety for generic scalings, while it drops if and only if the scaling vector is in the locus of the principal A-determinant.
