The development of John Aitchison's approach to compositional data analysis is followed since his paper read the Royal Statistical Society in 1982. logratio approach, which was proposed solve problematic aspects working with a fixed-sum constraint, summarized and reappraised. It maintained that properties on this originally built, main one being subcompositional coherence, are not required be satisfied exactly—quasi-coherence sufficient, near enough coherent for all practical purposes. This...
