"The text serves as a relevant and valuable reference for
practitioners in the fields of business, economics, and finance. In
addition, most students of econometrics are taught using GAUSS and
STATA, yet SAS is the standard in the working world; therefore,
this book is an ideal supplement for upper-undergraduate and
graduate courses in statistics, economics, and other social
sciences since it prepares readers for real-world careers."
