MiS Preprint Repository
We have decided to discontinue the publication of preprints on our preprint server end of 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.
Reciprocal maximum likelihood degrees of diagonal linear concentration models
Christopher Eur, Tara Fife, José Alejandro Samper and Tim SeynnaeveAbstract
We show that the reciprocal maximal likelihood degree (rmld) of a diagonal linear concentration model
In particular, this establishes the polynomiality of the rmld for general diagonal linear concentration models, positively answering a question of Sturmfels, Timme, and Zwiernik.
