Acknowledgments

This book is an update of A Step-by-Step Approach to Using the SAS System for Univariate and Multivariate Statistics by Larry Hatcher and Edward J. Stepanski. First and foremost, I want to thank Drs. Hatcher and Stepanski for the opportunity to revise this comprehensive text. I would like also to acknowledge Dr. Gina Graci for facilitating our collaboration. It is amazing the opportunities in life that arise due to sheer serendipity!

I would like to extend special thanks to Lynne Bresler, Kathleen Kiernan, Paul Marovich, and Catherine Truxillo for their invaluable technical review and constructive input during the revision process.

Finally, I must acknowledge the consistent support provided by the SAS Press group at SAS. In particular, thanks to Patsy Poole for her cheerful and rapid responses to my regular deluge of major and not-so-major questions. Thanks also to Mike Boyd for careful final editing, to Joan Stout for index editing, and to Candy Farrell for final composition.
