Covers the use of dynamic and interactive computer graphics in linear regression analysis, focusing on analytical graphics. Features new techniques like plot rotation. The authors have composed their own regression code, using Xlisp-Stat language called R-code, which is a nearly complete system for linear regression analysis and can be utilized as the main computer program in a linear regression course. The accompanying disks, for both Macintosh and Windows computers, contain the R-code and Xlisp-Stat.
An Instructor's Manual presenting detailed solutions to all the problems in the book is available upon request from the Wiley editorial department.

Understanding how a response variable depends on one or more predictor variables is a universal scientific problem. Regression analysis consists of ideas and methods for addressing this problem. Historically, regression methods have been largely numerical, with graphics playing an important but subsidiary role. By allowing informative and novel visualizations of regression data, modern computer hardware and software promise to reverse the historical roles of numerical and graphical regression methods. How shall this be done in practice? What can be learned from graphs and which graphs should be drawn? How can graphs be used to learn about fundamental features of regression problems? An Introduction to Regression Graphics answers these questions and more, providing the ideas, methodology, and software needed to use graphs in regression. From simple manipulations, such as changing the aspect ratio and marking points, to more sophisticated ideas like extracting smooths or looking at uncorrelated directions in 3D plots, R. Dennis Cook and Sanford Weisberg provide step-by-step software instructions and concise explanations of how graphs can be used in almost any regression problem. The accompanying disks?compatible with Macintosh, Windows, and UNIX workstations?contain an interactive regression program called R-code along with many sample data sets and demonstrations. The R-code is capable of performing all computations discussed in the book, and can be used with your own data. The book serves as a manual for the software. For data analysts, An Introduction to Regression Graphics provides new tools and insights for graphical analysis of regression data. For graduate and upper-level undergraduate students taking regression courses in the applied sciences, this book is a source for new methods and techniques that will continue to increase in importance for years to come.About the Author:
