Compositional Data Analysis in Practice Greenacre Michael Universitat Pompeu Fabra Barcelona Spain Paperback
Compositional Data Analysis in Practice is a user-oriented practical guide to the analysis of data with the property of a constant sum, for example percentages adding up to 100%. This book explains how this transformation affects the analysis, results and interpretation of this very special type of data. Compositional data can give misleading results if regular statistical methods are applied, and are best analysed by first transforming them to logarithms of ratios.
The applicability of these methods extends to other fields such as linguistics, All aspects of compositional data analysis are considered: visualization, modelling, dimension-reduction, clustering and variable selection, with many examples in the fields of food science, archaeology, sociology and biochemistry, and a final chapter containing a complete case study using fatty acid compositions in ecology.
