  • 2004): "Having accumulated a large library of books and papers on business, economic, and technology forecasting I can state without hesitation that Scott Armstrong's collection of 20 sections and 31 essays stands out as the best resource available. ... This is the definitive, methodologically exacting, and highly readable work on the subject."
    • Daniel M. Byrd III – "I thought that the Handbook reflected the consistent objective of a group of experts to interpret and explain forecasting. ...[F]or persons involved in (or hoping to become involved in) forecasting or its allied and subsidiary fields, such as risk analysis or econometrics, it will prove indispensable.
    • Paul Sheldon Foote - "The Web site for this book is a very valuable resource for forecasters."
  •, Kesten Green, Wellington, NZ: "The subtitle, A Handbook for Researchers and Practitioners, too narrowly defines the audience for Armstrong's new reference. Principles of Forecasting is, in fact, an indispensable resource for managers and professionals of every ilk.... I keep my copy handy, refer to it often, and learn something new every time I do so. How many books could one say that of?"

  • Australasian Journal of Market Research, July 2002, 10 (2), 35-45: Reviewer John Aitchison asks: "Why should a market researcher be interested in a book, and a big book at that, on "forecasting"? ... [D]oes it make sense to have one book with a scope as wide as this, one that attempts to meld quantitative and qualitative/judgmental prediction methods? ... I would have to answer “yes.” Principles of Forecasting ... succeeds admirably."
  • Business Economics, April 2002, 37 (2), 70-72: by Brandon Dupont, who says, "Overall, ... [the book] is a useful text for those business economists who are responsible for preparing forecasts on a regular basis."

  • European Association for Decision Making Bulletin , Winter 2003: A review by Carmel de Nahlik says, "The editor, the contributors and reviewers must be congratulated not only on a well-edited and integrated work, but also on heroic effort to produce such up-to-date papers. ... It is a challenge to think what can be added to the existing reviews of this book. Will I recommend our library buy it? Yes. Will I recommend it as reading for students? Yes too ..."
  • Financial Engineering News, April 2002, Issue 25: A lengthy review by John Aitchison recognizes "It is not a mathematically oriented text-book, not specifically focused on finance nor for that matter only on time-series forecasting. ...So why would a hard-nosed, empirical, finance person be interested in Principles of Forecasting? Precisely because of its broad scope. It takes a step back, reviews ALL the evidence about a diverse set of forecasting methodologies and provides a framework against which you can assess your own approaches and tools."

The principles can provide a process path to elaborating excellent forecasts. If you follow them, will you have guaranteed better accuracy? I guess that nobody can provide a warranty, but the probability of accuracy will be improved."
