class %DeepSee.extensions.clusters.PearsonGamma
extends %RegisteredObject
This class calculates Pearson-Gamma index which is a correlation coefficient
between distance between two points and a binary function whether they
belong to the same cluster.
Pearson-Gamma index is useful when clustering is used
for dimension reduction i.e. the process of reducing the number of
random variables under consideration
Validity indices are used in Cluster Validation
and determination of the optimal number of clusters.
