Abstract

We discuss methods of visualizing data and statistical models. The key innovation underlying these methods is that specialized graphs illustrate underlying patterns in data and they illustrate the properties of the statistical model that are used to analyze the data. These visualization techniques provide ways of understanding the underlying relation between variables, can illustrate how the statistical model works and can illustrate how the statistical model may not be capturing the underlying patterns among the variables.
