Maximum likelihood estimation for such models leads to the problem of maximizing the determinant function over a spectrahedron, and to the problem of characterizing the image of the positive definite cone under an arbitrary linear projection. These problems at the interface of statistics and optimization are here examined from the perspective of convex algebraic geometry."}],"oa":1,"status":"public","publication_status":"published","publist_id":"3332","type":"journal_article","publisher":"Springer","citation":{"chicago":"Sturmfels, Bernd, and Caroline Uhler. “Multivariate Gaussians, Semidefinite Matrix Completion, and Convex Algebraic Geometry.” <i>Annals of the Institute of Statistical Mathematics</i>.
