In D2MCS: Data Driving Multiple Classifier System

Feature-clustering based on Spearman Correlation Test.

Description

Performs the feature-clustering using Spearman's rho statistic.

Details

Spearman's rho statistic is to estimate a rank-based measure of association. These tests may be used if the data do not necessarily come from a bivariate normal distribution.
