Throughout his career, which included prominent professorships at the University of Illinois and the University of Nottingham, Newbold was renowned for his intellectual rigor. His most famous contribution to economics was a seminal 1974 paper co-authored with Clive Granger, which introduced the concept of "spurious regressions," a foundational insight for modern time-series analysis. It is this same unwavering dedication to accuracy and statistical precision that he brought to his pedagogical work, authoring the first edition of Statistics for Business and Economics . The textbook has since been updated through multiple editions, the most recent being the 10th edition, and is now co-authored with William L. Carlson and Betty M. Thorne.
