Compositional Data Analysis: Where Are We and Where Should We Be Heading? (2005, methodology): “The replacement method (Aitchison, 1986, p. 266) of rounded or trace zeros is not subcompositionally coherent and should now be replaced by the method arrived at independently by Fry, Fry and McLaren (2000) and Martin-Fernandez, Barcelo-Vidal and Pawlowsky-Glahn (2000), which preserve the ratios o”
