  1. The original Pearson correlation of the integration functions with the experimental data is reported in the column ρexp. The column ρmax/ ρmin reports the highest and the lowest Pearson correlation coefficients between the individual and the category functions associated with the category’s index. The column Dmin/Dmax reports the smallest and the largest distances between the individual and the category functions associated with the category’s index.
