A number of friends and colleagues, influential to my career, have reviewed both editions of the manuscript and provided constructive recommendations. The continued support from my manager, Mark Demers, SAS Institute Inc., encouraged me to rewrite the book.
I also want to thank Stacey Hamilton, my SAS editor; Mike Gilliland, SAS Institute Inc.; and Dr. Aric Labarr at North Carolina State University for their help with the editing of this manuscript. Their input and suggestions have enhanced the quality of the book. Finally, I thank my wife, Cheryl, again for keeping the faith all these years and supporting my career. Without her support and encouragement, I would not have been in a position to write this book.
