ACKNOWLEDGMENTS
I owe a great debt to Professors Paul Glewwe and Gerard McCullough (both from University of Minnesota) for teaching me everything I know about econometrics. Their instruction and detailed explanations formed the basis for this book. I am also grateful to Professor William Greene (New York University) for allowing me to access data from his text Econometric Analysis, 5th edition, 2003. The text by Greene is widely used to teach introductory graduate level classes in econometrics for the wealth of examples and theoretical foundations it provides. Professor Greene was also kind enough to nudge me in the right direction on a few occasions while I was having difficulties trying to program the many routines that have been used in this book.
I would also like to acknowledge the constant support I received from many friends and colleagues at Ameriprise Financials. In particular, I would like to thank Robert Moore, Ines Langrock, Micheal Wacker, and James Eells for reviewing portions of the book.
I am also grateful to an outside reviewer for critiquing the manuscript and for providing valuable feedback. These comments allowed me to make substantial improvements to the manuscript. Many thanks also go to Susanne Steitz-Filler for being patient with me throughout the completion of this book.
In writing this text, I have made substantial use of resources found on the World Wide Web. In particular, I would like to acknowledge Professors Jeffrey Wooldridge (Michigan State University) ...
