Pearson correlation coefficient of optimised 45 Clusters TN represented by the wavy circular node. The thickness of the arc represents the information contributed to the global structure. The strength of the arc is proportional to the strength of the probabilistic relation. The association of marginal probability to the modalities (outcome) of nodes is computed R, the Pearson's linear correlation coefficient between two nodes linked by an arc. The thickness of an arc is directly proportional to the absolute value of R. The blue indicated positive correlation and red a negative correlation. The exact value of the correlation for each arc is temporary displayed in the comment of the arc as indicated by the sign. The association of values to nodes' modalities and R, the Pearson's linear correlation coefficient between two nodes linked by an arc. If the modalities don't have associated values, default values are defined in order to compute R (from 0 to n-1 for a node with n modalities). The thickness of an arc is directly proportional to the absolute value of R, its colour represents the sign of R (blue if positive and red if not). The exact value of the correlation for each arc is temporary displayed in the comment of the arc.
