Compositional data cangive misleading results if regular statistical methods are applied,and are best analysed by first transformingthem to logarithms of ratios. This book explains how this transformationaffects the analysis, results and interpretation of this very special type ofdata. All aspects of compositional data analysis are considered: visualization,modelling, dimension-reduction, clustering and variable selection, with manyexamples in the fields of food science, archaeology, sociology andbiochemistry, and a final chapter containing a complete case study using fattyacid compositions in ecology. The applicability of these methods extends toother fields such as linguistics, geochemistry, marketing, economics andfinance.R SoftwareThe following repository contains data files and R scripts fromthe book https://github.com/michaelgreenacre/CODAinPractice.
