| Statistics Toolbox | |
The Statistics Toolbox provides an interactive graphical user interface (GUI) to make comparison of competing models more understandable. You can explore the GUI using the Hald (1960) data set. Here are the commands to get started.
The Hald data come from a study of the heat of reaction of various cement mixtures. There are four components in each mixture, and the amount of heat produced depends on the amount of each ingredient in the mixture.
The interface consists of three interactively linked figure windows. Two of these are discussed in the following sections:
All three windows have hot regions. When your mouse is above one of these regions, the pointer changes from an arrow to a circle. Clicking on this point initiates some activity in the interface.
