Usually books on regression analysis deal with only linear regression. This text includes thorough coverage of the standard regression topics but also includes chapters on logistic regression, nonparametric regression, robust regression, ridge regression and nonlinear regression. Recent tools including the bootstrap are covered. Software for ridge regression is discussed and a Minitab macro is given in Appendix A. Software is also provided in the attached diskette with installation instructions in Appendix A.Ryan is an excellent writer who does not assume a high level of mathematical sophistication. He has also written an earlier text on statistical quality control "Statistical Methods for Quality Improvement" which came out in a second edition earlier this year.
