This book offers an introductory-level guide to the complex field of multivariate analytical
calibration with particular emphasis on real applications such as near infrared spectroscopy.
It presents intuitive descriptions of mathematical and statistical concepts illustrated with a
wealth of figures and diagrams and consistently highlights physicochemical interpretation
rather than mathematical issues. In addition it describes an easy-to-use and freely available
graphical interface together with a variety of appropriate examples and exercises. Lastly it
discusses recent advances in the field (figures of merit detection limit non-linear
calibration method comparison) together with modern literature references.
