%description
Clustering and classification inference for high dimension low sample size
(HDLSS) data with U-statistics. The package contains implementations of
nonparametric statistical tests for sample homogeneity, group separation,
clustering, and classification of multivariate data. The methods have high
statistical power and are tailored for data in which the dimension L is
much larger than sample size n. See Gabriela B. Cybis, Marcio Valk and
