ACKNOWLEDGMENTS

I would like to thank Robert Rodriguez and Phil Gibbs for pointing out
the need for a book about simulating data in SAS.  "Simulation" is a
vast topic, and early discussions with them helped me to whittle down
the possible topics. Bob and Maura Stokes provided many opportunities
for me to develop this material by inviting me to present papers and
workshops at conferences.  My supervisors at SAS fully supported me as
I prepared for and participated in these conferences.

I thank the many SAS users who encouraged me to write a book that
emphasizes the practical side of simulation. Discussions with SAS
users helped me to determine what topics are of practical importance
to statisticians and analysts in business and industry.

I thank my colleagues at SAS from whom I have learned many statistical
and programming techniques. Special thanks to Randy Tobias, who always
provides sound advice and statistical wisdom for my naive questions.
Thanks also to Tim Arnold and Warren Kuhfeld for their 'saslatex'
documentation system that automatically produced all tables and graphs
in this book from the programs that appear in the text.

I thank my editor, John West, and the other employees at SAS Press for
their work producing and promoting the book. I thank two reviewers,
Clement Stone and Bob Pearson, who provided insightful comments about
the book's content and organization.

Thanks to several colleagues and friends who read and commented on
early drafts of this book. This includes the following individuals:
Rob Agnelli, Jason Brinkley, Tonya Chapman, Steve Denham, Bruce
Elsheimer, Betsy Enstrom, Phil Gibbs, Emily Lada, Pushpal
Mukhopadhyay, Bill Raynor, Robert Rodriguez, Jim Seabolt, Udo Sglavo,
Ying So, Jill Tao, Randy Tobias, Ian Wakeling, Donna Watts, and Min
Zhu.

Finally, I would like to thank my wife, Nancy, for her constant
support, and my parents for instilling in me a love of learning.
