(synopsis "Depth-Based classification and calculation of data depth")
(description
"This package contains procedures for depth-based supervised learning,
which are entirely non-parametric, in particular the DDalpha-procedure (Lange,
Mosler and Mozharovskyi, 2014). 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.")
