• Sommario/riassunto: This book is aimed at the large number of people who need to use chemometrics but do not wish to understand complex mathematics, therefore it offers a comprehensive examination of the field of chemometrics without overwhelming the reader with complex mathematics. * Includes five chapters that cover the basic principles of chemometrics analysis.* Provides two chapters on the use of Excel and MATLAB for chemometrics analysis.* Contains 70 worked problems so that readers can gain a practical understanding of the use of chemometrics.
