Applied Statistics (2nd edition) CD
1 CD Contents
The contents of the CD are as follows:
· Datasets in the form of Excel files for statistical experiments.
· Tools for specific statistical procedures.
Both datasets and tools are described in detail in the book.
2 System Requirements
· PC with CD player, running Windows 98 SE, Windows NT 3 SP4 or later with Microsoft Excel 2003.
· A minimum of 17 Mbytes should be available in the Hard Disk in order to install all datasets (14.1 Mbytes) and tools (2.4 Mbytes).
· A minimum of 128 Mbytes RAM and 550 MHz processor rate are recommended for acceptable performance.
· Matlab
3 Installation
· Datasets and Tools.xls are simply copied from the CD to the destination directory.
· Matlab functions are usually copied from the CD to the Matlab "work" directory. Other alternative directories are also possible (see Matlab manual).
· R functions are text files that should be pasted into the R console.
· The SCSize tool is provided with a setup.exe file for installation by either running the setup.exe file from the Run option of the Start menu or by using the Add/Remove Programs option of the Control Panel option in Settings. Next, simply follow the instructions. Before installation it is advisable to first close all open programs.
4 Using SCSize
SC Size (Statistical Classifier Design)
Displays a graphic of the following variables, for a two-class linear classifier with specified Battacharrya distance and for several values of the dimensionality ratio (number of patterns per class/dimension):
· Bayes error;
· Expected design set error (resubstitution method);
· Expected test set error (holdout method).
The standard deviations of the error estimates are also displayed when the mouse is clicked over a selected point of the picture box.
The user must specify:
· Dimension d (£ 10).
· Square of the Battacharrya distance, computable by several statistical software products, and usually called square Mahalanobis distance (of the class means).
