Notes
As a comment, Greenacre (2011) published a paper “Measuring subcompositional incoherence” to show that the ideal of subcompositional coherence could be approximated by some methods that are not logratio-based. The proposed quantitative measurement of incoherence (i.e. lack of coherence) was quite straightforward and many numerical examples were included. Yet in the present paper the authors, at the end of Sect. 2.1, misrepresent this approach by saying, in their defence of strict coherence: “Incoherence is, in general, difficult to measure, or even check, numerically (Greenacre 2011)”.
