Applied Compositional Data Analysis Filzmoser Peter
This book presents the statistical analysis of compositional data using the log-ratio approach. In addition, it considers special data structures like high-dimensional compositions and compositional tables. It includes a wide range of classical and robust statistical methods adapted for compositional data analysis, such as supervised and unsupervised methods like PCA, correlation analysis, classification and regression.
It focuses on practical aspects of compositional data analysis rather than on detailed theoretical derivations, thus issues like graphical visualization and preprocessing (treatment of missing values, zeros, outliers and similar artifacts) form an important part of the book. The methodology introduced is also frequently compared to methods which ignore the specific nature of compositional data. Since it is primarily intended for researchers and students from applied fields like geochemistry, chemometrics, biology and natural sciences, economics, and social sciences, all the proposed methods are accompanied by worked-out examples in R using the package robCompositions.
