The Bayesian posterior inference in the hierarchical model is able to compare these two sources of variability, taking into account the prior belief and the information from the data. When the regression model has errors that have a normal distribution, and if a particular form of the prior distribution is assumed, explicit results are available for the posterior probability distributions of .
