Statistics of compositional data

Gerald van den Boogaart
Technical University Freiberg, Germany

The workshop will teach statistics of compositional data analysis using R and the R package compositions. Compositional data is characterised by the fact that the sum is an artefact of the measurment process (e.g. a constant like100%) and not meaningfull for process to analysed. Analysing compositional data with classical multivariate tools leads to many artefacts. However the so called "working in coordinates principle" allows to create similar tools for statistical analysis especially adapted for compositional data.

Participants are expected to bring a laptop or computer to the workshop with R and the R package compositions installed.) The help with installing the package can be offered by the instructures prior to the workshop during the conference. Instructures are Gerald van den Boogaart and Matevz Bren, two of the authors of the compositions package.
