Detailed Description

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.
