This section describes how to set up a multiple linear regression model how to specify prior distributions for regression coefficients of multiple predictors and how to make Bayesian inferences and predictions in this setting. It is really worth spending time on this figure because it captures some key ideas in Bayesian inference. 7 explaining Bayesian linear regression and I ve reproduced a version of that figure with my own implementation of Bayesian linear regression my Figure 1 1 1 . In the first stage a single best model is defined by a specific selection of relevant predictors in the second stage the regression coefficients of the winning model are used for prediction and for inference concerning the importance of the predictors. The rstanarm package aims to address this gap by allowing R users to fit common Bayesian regression models using an interface very similar to standard functions R functions such as lm and glm .
