WebTitle: Bayesian decomposable graphical models which are discrete and parametric. Abstract: Discrete graphical models are typically non-parametric with unknowns being cell probabilities in a multiway table. In contrast, continuous graphical models are Gaussian and thus fully parametric, which considerably reduces the number of unknowns.

WebBayesian analysis is a statistical method that makes inference on unknown quantities of interest (which could be param- eters in a model, missing data, or predictions) by combining prior beliefs about the quantities of interest and information (or evidence) contained in an observed set of data.
