Websetting, Gaussian graphical models are based on hierarchical specifications for the covariance matrix (or precision matrix) using global conjugate priors on the space of positive-definite matrices, such as the inverse Wishart (IW) prior or its equivalents. Dawid and Lauritzen (1993) introduced an equiva-lent form as the hyper-IW (HIW) distribution.
