good properties of both. The first is a biplot based on the logratio approach to compositional data analysis. This approach … the logratio biplot, we obtain a method which obeys both principles of subcompositional coherence and distributional …

The singular value decomposition and its interpretation as a linear biplot has proved to be a powerful tool for … analysing many forms of multivariate data. Here we adapt biplot methodology to the speciffic case of compositional data …, showing how the singular value decomposition can achieve an accurate biplot of the colour ratios and how possible models …
