Graphical gaussian modeling

Websubsumes Gaussian graphical models (i.e., the undirected Gaussian models) as a special case. In this paper, we directly approach the prob-lem of perfectness for the Gaussian graphical models, and provide a new proof, via a more transparent parametrization, that almost all such models are perfect. Our approach is based on, and … WebSte en Lauritzen University of Oxford Gaussian Graphical Models.
