The book is edited by Professor J. Scott Armstrong of the Wharton School at the University of Pennsylvania, and is published by Kluwer Academic Publishers. Contributions were made by 40 leading experts in forecasting. The 30 chapters cover all types of forecasting methods. There are judgmental methods, such as Delphi, role-playing, and intentions studies. Quantitative methods include econometric methods, expert systems, and extrapolation. Some methods, such as conjoint analysis, analogies, and rule-based forecasting, integrate quantitative and judgmental procedures. In each area, the authors identify what is known in the form of "if-then principles," and they summarize evidence on these principles. The book includes the first comprehensive forecasting dictionary.
The project, developed over a four-year period, represents the first book to summarize all useful knowledge about forecasting and to present it in the form of principles that can be used by researchers and practitioners. To ensure that the principles are correct, the authors reviewed one another's papers. In addition, external reviewers were provided by more than 120 experts, some of whom reviewed many of the papers.
Professor Armstrong is the author of Long Range Forecasting and a founder of the Journal of Forecasting, the International Journal of Forecasting, the International Institute of Forecasting, and the International Symposium on Forecasting.
