Webfor purely discrete data and the covariance selection models [Dempster (1972)] for purely continuous data. In Frydenberg and Lauritzen (1989), the central concept of decomposition of a graphical interaction model was considered. In the present work we will look at another important concept: collapsibility. WebConsidering the covariance selection problem of multivariate normal distributions, we show that its Fenchel dual formulation is insightful and allows one to calculate direct estimates under decomposable models. We next generalize the covariance ...

Webcovariance matrix. This type of sparsity naturally connects with the problem of covariance selection (Dempster, 1972) and Gaussian graphical models (see, e.g., Whittaker, 1990; Lauritzen, 1996; Ed-wards, 2000), which makes it particularly appealing in a number of applications. Methods to exploit such sparsity have been proposed recently. humana nursing jobs at homeWeb(Dempster, 1972) ⇒ Arthur P. Dempster. (1972). “Covariance Selection.” In: Biometrics, 28.
