John Aitchison spent much of his career addressing the unique challenges of statistics for compositional data. His legacy is being carried on by colleagues who do not always succeed in presenting the material in a way that is understandable to geoscientists. Now in the fourth part of a series of blog posts, I am attempting to address the problems of closed data and possible workarounds using a series of simple MATLAB simulations, without frustrating geoscientists with mathematical formulas.
