J. Scott Armstrong, ed., Principles of Forecasting, 2001. This summary of knowledge from experts and empirical studies provides guidelines that apply to economics, sociology, psychology and other fields. It addresses problems related to finance (How much is this company worth?), marketing (Will a new product be successful?), personnel (How can we identify the best job candidates?), and production (What level of inventories should be kept?). Edited by Professor J. Scott Armstrong of the Wharton School, University of Pennsylvania, this book contains contributions by 40 leading experts in forecasting. The 30 chapters cover all types of forecasting methods: judgmental methods, such as Delphi, role-playing, and intentions studies and quantitative methods, including 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 summarize evidence on these principles. The book also includes the first comprehensive forecasting dictionary. Developed over a four-year period, the book presents knowledge in the form of principles that can be used by researchers and practitioners. To ensure accuracy, the authors reviewed one another’s papers. In addition, 122 external reviewers made suggestions.
J. Scott Armstrong, Long-Range Forecasting: From Crystal Ball to Computer, John Wiley and Sons, 1985 (second edition). Designed to answer the question “Which forecasting method is the best to use in a given situation?” this book covers judgmental, extrapolation, and econometric methods. It shows how to combine forecasts and describes how to evaluate and compare different forecasting methods. The conclusions are based on the author’s research as well as on over 1050 books and papers on forecasting in economics, sociology, medicine, politics, weather, finance, personnel, marketing, and other areas. The book describes this vast array of literature. This second edition is out of print but is available online in a pdf of the full text.

Fildes, Robert and Ord, Keith, Principles of Business Forecasting, July 2012 by Cengage, is a new book by Lancaster University Management School’s Robert Fildes and Keith Ord of Georgetown University.
Forecasting is important to almost all organisations, witness the problems encountered in the London 2012 Olympics. All too often it’s a topic that gets too little serious attention, both in business and management courses and also within organisations where it is much needed. The Ord/Fildes book serves both as a textbook for students and as a reference book for experienced forecasters in the many fields where forecasting is applied.
The book introduces both standard and advanced forecasting methods and their underlying models, and also includes general principles to guide and simplify forecasting practice. The overall aim remains one of ensuring the techniques can be applied. A key strength of the book is its emphasis on real data sets, taken from government and business sources and used in each chapter’s examples and exercises. Forecasting techniques are demonstrated using a variety of software platforms and the companion website provides easy-to-use Excel® macros to support the basic methods.
Robert Fildes, et al., A Bibliography of Business and Economic Forecasting. This work is available in full text and as a searchable index on the Forecasting principles site. The authors provide keywords to describe each study allowing the reader to search for relevant studies not available on other electronic searches. It covers literature from 1965 through 1981 from over 50 journals and a number of books, describing 5,436 papers on forecasting.
Hyndman, R.J., Koehler A.B., Ord, J.K., Snyder, R.D. Forecasting with Exponential Smoothing: The State Space Approach, Springer-Verlag, 2008.. Exponential smoothing methods have been around since the 1950s, and are still the most popular forecasting methods used in business and industry. Recently, exponential smoothing has been revolutionized with the introduction of a complete modeling framework incorporating innovations state sapce models, likelihood calculation, prediction intervals and procedures for model selection. In this book, all of the important results are brought together in a coherent manner with consistent notation. In addition, many new results and extensions are introduced and several application areas are examined in detail.
Hans Levenbach and James P. Cleary, Forecasting: Practice and Process for Demand Management, Thomson/Brooks-Cole, 2006.This text introduces students to the forecasting principles, applications, and methods of demand forecasting. L&C stress applications in their book, presenting concepts in the context of real examples drawn from their own broad experience as forecasting practitioners in industry, consultants to organizations, and educators. It also addresses the macroeconomic forecasting procedures used by economists as well as the specific product-level forecasting techniques now widely used by corporate sales and operations planning organizations—providing comprehensive coverage of traditional and advanced forecasting tools. Throughout, the authors focus more on training students to perform accurate data analysis than on modeling sophistication. The text incorporates computing throughout the book, featuring Microsoft® Excel applications and including a free copy of anl Excel add-in, called PEERForecaster.xla and data sets on CD.
Spyros Makridakis, Steven Wheelwright and Rob Hyndman, Forecasting: methods and applications, John Wiley and Sons, 1998 (third edition). This book, sometimes known as the “Bible of forecasting”, is the best-selling introductory text in business forecasting. It covers the full range of major forecasting methods and provides a complete description of their essential characteristics including the steps needed for their practical application. The book avoids getting bogged down in the theoretical details that are not essential to understanding how the various methods work, and provides a systematic comparison of the advantages and drawbacks of various methods so that the most appropriate method can be selected for each forecasting situation. It covers a comprehensive set of forecasting horizons (from the immediate to the long term) and approaches to forecasting (time series, explanatory, judgemental, mixed).
