Proof of a conjecture of Sturmfels, Timme and Zwiernik (2108.11085v1)
Published 25 Aug 2021 in math.AG
Abstract: We prove a conjecture of Sturmfels, Timme and Zwiernik on the ML-degrees of linear covariance models in algebraic statistics. As in our previous works on linear concentration models, the proof ultimately relies on the computation of certain intersection numbers on the varieties of complete quadrics.
