Sensitivity {RSKC}

Compute the sensitivities (probability of true positive) of each cluster

Description

The sensitivity or conditional probability of the correct classification of cluster k is calculated as follows: First, the proportions of observations whose true cluster label is k are computed for each classified clusters. Then the largest proportion is selected as the conditional probability of the correct classification. Since this calculation can return 1 for sensitivities of all clusters if all observations belong to one cluster, we also report the observed cluster labels returned by the algorithms.

Usage

Sensitivity(label1, label2)

Arguments

label1

A vector of length N, containing the cluster labels from any clustering algorithms.

label2

A vector of length N, containing the true cluster labels.
