Relation between predictors and refractive index (RI). (a) Illustrates the relation between RI and \(E_g\), while (b,c) show RI as a function of the mean and standard deviation of electronegativity (\(\chi\)), respectively. (d,e) illustrate the dependence of RI on the mean and standard deviation of first ionization energy (I).
