Supplement material for the paired t-test:


We calculate the mean of the cR over all data sets in two different contexts: (A) taking into account, for each data set, only the

partition with the number of clusters equals to the number of actual classes in the respective data set, and (B) considering, for each data set, the partition that presents the best cR, independently of its number of cluster. In the case of the data for the paired t-test to check if differences in the cR between distinct method  are statistical significant, given that we are mainly interested in comparing the clustering methods, we selected for each context, only the results with the proximity measure, which displayed the largest mean of cR.
