Linear Regression with Sparsely Permuted Data
Martin Slawski, Emanuel Ben-David
In regression analysis of multivariate data, it is tacitly assumed that response and predictor variables in each observed response-predictor pair correspond to the same entity or u…
The Letac-Massam conjecture and existence of high dimensional Bayes estimators for Graphical Models
Emanuel Ben-David, Bala Rajaratnam
In recent years, a variety of useful extensions of the Wishart have been proposed in the literature for the purposes of studying Markov random fields/graphical models. In particula…
Sharper lower and upper bounds for the gaussian rank of a graph
Emanuel Ben-David
An open problem in graphical Gaussian models is to determine the smallest number of observations needed to guarantee the existence of the maximum likelihood estimator of the covari…
Maximal Invariants Over Symmetric Cones
Emanuel Ben-David
In this paper we consider some hypothesis tests within a family of Wishart distributions, where both the sample space and the parameter space are symmetric cones. For such testing…
Maximal Invariants For Lorentz Wishart Models
Emanuel Ben-David
In this paper we consider two statistical hypotheses for the families of Wishart type distributions. These distributions are analogs of the Wishart distributions defined and parame…
High dimensional Bayesian inference for Gaussian directed acyclic graph models
Emanuel Ben-David, Tianxi Li, Helene Massam +1
We study centered Gaussian models Markov with respect to a directed acyclic graph (DAG) whose vertices have a fixed parent ordering. We construct a conjugate family on the modified…
