David F. Hendry is Professor of Economics at the University of Oxford and a Fellow of Nuffield College. Bent Nielsen is Reader in Econometrics at the University of Oxford and a Fellow of Nuffield College

"Hendry and Nielsen's somewhat unusual data-driven approach works well...providing genuine insights at a reasonably advanced level."--John Hudson, Times Higher Education "Summing up: A remarkable achievement, a beautiful piece of work, engaging the reader quickly with the subject matter, Econometric Modeling provides a good introduction to the field for aspiring and advanced students and also contains valuable material and hints for experts already well versed in the subject. A must-buy for the library."--Current Engineering Practice
