GeoCoDA: Recognizing and Validating Structural Processes in Geochemical Data. A Workflow on Compositional Data Analysis in Lithogeochemistry
Eric Grunsky, Michael Greenacre, Bruce Kjarsgaard
Geochemical data are compositional in nature and are subject to the problems typically associated with data that are restricted to the real non-negative number space with constant-…
The chiPower transformation: a valid alternative to logratio transformations in compositional data analysis
Michael Greenacre
The approach to analysing compositional data has been dominated by the use of logratio transformations, to ensure exact subcompositional coherence and, in some situations, exact is…
A Guideline for the Statistical Analysis of Compositional Data in Immunology
Jinkyung Yoo, Zequn Sun, Michael Greenacre +3
The study of immune cellular composition has been of great scientific interest in immunology because of the generation of multiple large-scale data. From the statistical point of v…
Aitchison's Compositional Data Analysis 40 Years On: A Reappraisal
Michael Greenacre, Eric Grunsky, John Bacon-Shone +2
The development of John Aitchison's approach to compositional data analysis is followed since his paper read to the Royal Statistical Society in 1982. Aitchison's logratio approach…
Three approaches to supervised learning for compositional data with pairwise logratios
Germa Coenders, Michael Greenacre
The common approach to compositional data analysis is to transform the data by means of logratios. Logratios between pairs of compositional parts (pairwise logratios) are the easie…
Compositional data analysis -- linear algebra, visualization and interpretation
Michael Greenacre
Compositional data analysis is concerned with multivariate data that have a constant sum, usually 1 or 100\%. These are data often found in biochemistry and geochemistry, but also…
