From: Cluster analysis of replicated alternative polyadenylation data using canonical correlation analysis
Cluster analyses of real poly(A) site data set based on relative abundance. Standardized cluster validation scores for various performance indexes with the increasing of the number of clusters were calculated, including CON (a), DUNN(b), AD (c), ADM (d), and BHI (e). Larger scores indicate better performance. Without knowing the true number of clusters in a given data set, variable number of clusters ranging from 5 to 20 was set. (f) Number of genes in clusters obtained from PASCCA using poly(A) site data set characterized by abundance or relative abundance
