1. Assessment of Covariance Selection Methods in High-Dimensional Gaussian Graphical Models
ABSTRACT The covariance selection in Gaussian graphical models consists in selecting, based on a sample of a multivariate normal vector, all those pairs of variables that are conditionally dependent given the remaining variables. This problem is equivalent to estimate the graph identifying the nonzero elements on the off-diagonal entries of the precision mat
