# Reciprocal Maximum Likelihood Degrees of Brownian Motion Tree Models

@article{Boege2020ReciprocalML, title={Reciprocal Maximum Likelihood Degrees of Brownian Motion Tree Models}, author={T. Boege and Jane Ivy Coons and C. Eur and Aida Maraj and Frank Rottger}, journal={arXiv: Statistics Theory}, year={2020} }

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.
