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 st...

We consider the problem of measurements made by several laboratories (or methods) on virtually the same object of interest. In general, the number of measurements made at each laboratory may differ. Moreover, the laboratories may exhibit the between-laboratory variability caused by the systematic error due to each laboratory, as well as different within-laboratory variances caused by different ...
