A positive definite completion problem pertains to determining whether the unspecified positions of a partial (or incomplete) matrix can be completed in a desired subclass of positive definite matrices. In this paper we study an important and new class of positive definite completion problems where the desired subclasses are the spaces of covariance and(More)
The Wishart distribution, defined on the open convex positive definite cone, plays a central role in multivariate analysis and multivariate distribution theory. Its domain of integrability is often referred to as the Gindikin set. In recent years, a variety of useful extensions of the Wishart have been proposed in the literature for the purposes of studying(More)
