WebSep 27, 2007 · However, if a log-linear model m is a decomposable graphical model, then the hyper-Dirichlet family, a class of prior distributions that is based on the Dirichlet distribution for the saturated model (no log-linear constraints) and developed by Dawid and Lauritzen (1993), provides an attractive alternative, for which posterior computation is ...
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.
