  Discussion on "Random-projection ensemble classification" by T. Cannings and
R. Samworth. We believe that the proposed approach can find many applications
in economics such as credit scoring (e.g. Altman (1968)) and can be extended to
more general type of classifiers. In this discussion we would like to draw
authors attention to the copula-based discriminant analysis (Han et al. (2013)
and He et al. (2016)).
