Bayesian Multiple Linear Regression Example. In statistics Bayesian linear regression is an approach to linear regression in which the statistical analysis is undertaken within the context of Bayesian inferenceWhen the regression model has errors that have a normal distribution and if a particular form of prior distribution is assumed explicit results are available for the posterior probability distributions of the models parameters.
