Statistical analysis of compositional data. Theory and applications to Earth Sciences
Almost every discipline in Earth Sciences must deal with compositional data. These are data that are presented in percentages or relative contributions of the single variables to the whole. As such, they carry only relative information and standard statistical methods can lead to questionable results if they are directly applied on the original compositional data. New tools for their analysis have been developed in recent years, which open up a new field of research and a new perspective for understanding natural processes. The aims of this session are to encourage developments in the theory of these new quantitative techniques and foster their application to geological data set.
