Fig. 2: Basic relationships among the descriptors.

From: Predicting permeation of compounds across the outer membrane of P. aeruginosa using molecular descriptors

Fig. 2

Each data point represents a molecule, and it is projected on the two-dimensional space of two descriptors as shown. Some of the most common properties found among the descriptors are: a linear correlations, b non-linear correlations, and c uncorrelated. The numbers on each of the panels are computed by standard correlations (i.e., Pearson coefficient), Cij, and rank correlations, Rij. As shown, rank correlations capture better the non-linear relationship shown in the central panel.
