%description
Includes the reference implementation of Genie - a hierarchical clustering
algorithm that links two point groups in such a way that an inequity
measure (namely, the Gini index) of the cluster sizes does not
significantly increase above a given threshold. This method most often
outperforms many other data segmentation approaches in terms of clustering
quality as tested on a wide range of benchmark datasets. At the same time,
Genie retains the high speed of the single linkage approach, therefore it
is also suitable for analysing larger data sets. For more details see
(Gagolewski et al. 2016 <DOI:10.1016/j.ins.2016.05.003>). For an even
faster and more feature-rich implementation, including, amongst others,
noise point detection, see the 'genieclust' package.
