%description
Contains procedures for depth-based supervised learning, which are
entirely non-parametric, in particular the DDalpha-procedure (Lange,
Mosler and Mozharovskyi, 2014 <doi:10.1007/s00362-012-0488-4>). The
training data sample is transformed by a statistical depth function to a
compact low-dimensional space, where the final classification is done. It
also offers an extension to functional data and routines for calculating
certain notions of statistical depth functions. 50 multivariate and 5
functional classification problems are included. (Pokotylo, Mozharovskyi
and Dyckerhoff, 2019 <doi:10.18637/jss.v091.i05>).
