Vol 12/1! 2001)"This book is recommended to students of chemical! biochemical and food engineering! scientists and industrial practitioners". (Chemical Biochemical Engineering! June 2001)"a possible source of inspiration" (Measurement Science Technology! October 2001)"a powerful and versatile methodology" (Chemie Plus! June 2001)"...should prove a very useful text for this target readership." (Short Book Reviews! Vol. 22! No. 1! April 2002) Informationen zum Autor Harald Martens, Professor of Chemometrics, Norwegian University of Science and Technology, and Technical University of Denmark. He is co-author of the best selling book, Multivariate Calibration, also published by John Wiley & Sons. He has won many awards for his work in data analysis including in 1999 the Galactic Industries Prize and the Herman World medal. His present developments have also been incorporated by CAMO Inc in their latest version of The Unscrambler. Magni Martens, Professor of Sensory Science, Royal Veterinary & Agricultural University, Denmark. She has also won awards for her work in sensory science including in 2000 the prestigious Carlsberg Research Foundation proze. She has published numerous papers on multivariate data analysis for relating "soft" human quality perception to "hard" facts and measurements. Klappentext Multivariate data analysis is a central tool whenever several variables need to be considered at the same time. The present book explains a powerful and versatile way to analyse data tables, suitable also for researchers without formal training in statistics. This method for extracting useful information from data is demonstrated for various types of quality assessment, ranging from human quality perception via industrial quality monitoring to health quality and its molecular basis. Key features include: * Minimum mathematics; all technical details in appendix form * Very accessible style with cartoons, self assessment questions and wide range of practical examples * All data sets available FREE online on Chemometrics World (http://www.wiley.co.uk/wileychi/chemometrics). Essential reading for researchers who need data analysis in practice, it will be of particular interest to chemometricians, sensometricians and food scientists already familiar with Harald's previous book. The book is written with ISO certified businesses and laboratories in mind, to enhance Total Quality Management (TQM). As yet there are no clear guidelines for realistic data analysis of quality in complex systems - this volume bridges the gap. Zusammenfassung Die Datenanalyse mit mehreren Variablen gehört zum Alltag der Chemometrie. Die Autoren sind ausgezeichnete Spezialisten auf dem Gebiet der multivariaten Analyse. Sie geben hier in saloppem Stil und aufgelockert durch zahlreiche witzige Cartoons eine verständliche Einführung in dieses Thema. Erläutert werden eine Reihe von Anwendungen bei der Qualitätskontrolle, insbesondere in der Nahrungsmittelindustrie. Mit zahlreichen Kontrollfragen und Übungsaufgaben! Inhaltsverzeichnis Preface.
