Bayes linear statistics Wikipedia. The aim of Bayesian Linear Regression is not to find the single вЂњbestвЂќ value of the model parameters, but rather to determine the posterior distribution for the model parameters. Not only is the response generated from a probability distribution, but the model parameters are assumed to come from a distribution as well. The posterior probability of the model parameters is conditional upon, Bayesian Information Criterion (also called the Schwarz criterion): given a set of models to choose from, you should choose the model with the lowest BIC. BernsteinвЂ“von Mises theorem: This is the Bayesian equivalent of the asymptotic normality results in the asymptotic theory of maximum likelihood estimation (Ghosh & Ramamoorthi, 2006, p.33)..
