In this revision of their 1984 book The Modern Forecaster , Levenbach (president, Delphus Inc., a software-development and sales-consulting firm) and Cleary (a frequent corporate marketing and finance officer) present explanations of the most widely accepted and practiced quantitative methods in business forecasting. After first covering traditional approaches of a number of problems, they treat resistant (safeguarding against unusual values) and robust (safeguarding against departures from classical statistical assumption) alternatives to the same problems. Over the course of the book they include statistical forecasting tools in exploratory data analysis, elements of robust/resistant estimation, regression diagnostics, and state-space models. Included on the CD-ROM is an Excel spreadsheet software add-in to aid students with the exercises and examples in the text. Annotation ©2005 Book News, Inc., Portland, OR (booknews.com)
