class %DeepSee.extensions.clusters.PearsonGamma extends %Library.RegisteredObjectThis 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.
