By comparison, prediction in frequentist statistics often involves finding an optimum point estimate of the parameter s —e. In Bayesian statistics, however, the posterior predictive distribution can always be determined exactly—or at least, to an arbitrary level of precision, when numerical methods are used. Usually, VE selects the next variable to be eliminated such that a new potential of minimum size is generated during the elimination process. Inference over exclusive and exhaustive possibilities[ edit ] If evidence is simultaneously used to update belief over a set of exclusive and exhaustive propositions, Bayesian inference may be thought of as acting on this belief distribution as a whole.

CAs create a variable elimination sequence in order to triangulate the moral graph; usually, the next variable to be eliminated is selected such that a new clique of minimum size is created during the elimination process.
