| Abstract: | Graphical model validation techniques for linear normal models are often used to check the assumptions underlying a statistical model. We describe an approach to provide ‘instant experience’ in looking at a graphical model validation plot, so it becomes easier to validate if any of the underlying assumptions are violated. |
