Compositional data represent a specific family of multivariate data, where the information of interest is contained in the ratios between parts rather than in absolute values of single parts. The analysis of such specific data is challenging as the application of standard multivariate analysis tools on the raw observations can lead to spurious results. Hence, it is appropriate to apply certain transformations prior further analysis. One popular multivariate data analysis tool is independent…

Principal component analysis for compositional data with outliers
TLDR
It turns out that the procedure using ilr‐transformed data and robust PCA delivers superior results to all other approaches, demonstrating that due to the compositional nature of geochemical data PCA should be carried out without an appropriate transformation.
Compositional data analysis : theory and applications
TLDR
This book presents the history and development of compositional data analysis along with Aitchison's log-ratio approach, and describes the state of the art both in theoretical fields as well as applications in the different fields of science.
PLS‐DA for compositional data with application to metabolomics
When quantifying information in metabolomics, the results are often expressed as data carrying only relative information. Vectors of these data have positive components, and the only relevant…
robCompositions: An R‐package for Robust Statistical Analysis of Compositional Data
TLDR
The R-package robCompositions (Templ et al., 2009) contains functions for robust statistical methods designed for compositional data, like principal component analysis, factor analysis, and discriminant analysis.
Blind Source Separation for Spatial Compositional Data
TLDR
A novel blind source separation approach for spatially dependent data is suggested and the results are compared to the results coming from marginal principal component analysis and independent component analysis that ignore spatial dependence.
Compositional data: the sample space and its structure
The log-ratio approach to compositional data (CoDa) analysis has now entered a mature phase. The principles and statistical tools introduced by J. Aitchison in the eighties have proven successful in…
Groups of Parts and Their Balances in Compositional Data Analysis
Amalgamation of parts of a composition has been extensively used as a technique of analysis to achieve reduced dimension, as was discussed during the CoDaWork'03 meeting (Girona, Spain, 2003). It was…
Invariant Coordinate Selection
A general method for exploring multivariate data by comparing different estimates of multivariate scatter is presented. The method is based upon the eigenvalue-eigenvector decomposition of one…
Linear regression with compositional explanatory variables
TLDR
An approach based on the isometric logratio (ilr) transformation is used and it turns out that the resulting model is easy to handle, and that parameter estimation can be done in like in usual linear regression.
Fourth Moments and Independent Component Analysis
In independent component analysis it is assumed that the components of the observed random vector are linear combinations of latent independent random variables, and the aim is then to find an…
