Correlation matrix (Pearson’s) involving the main optical (Hβ and [O III]λ5007), radio and IR derived parameters. The limits in the color ranges correspond to a statistical significance of ±1, 2, 3σ for the Pearson’s correlation coefficient computed for 18 objects. The parameters considered are in this order, the bolometric luminosity L, the black hole mass M_BH, the Eddington ratio L/L_Edd, the radio power at 1.4 GHz, the radio spectral index α, Fe II prominence ratio R_FeII, the equivalent with of Hβ (broad components), its FWHM and centroid displacement at one-half peak intensity $c(\frac{1}{2})$, the mass outflow rate measured from blueshift emission of Hβ, Ṁ; the equivalent width, FWHM, $c(\frac{1}{2})$, Ṁ of the [O III]λ5007 line; the Q parameters defined according to Yun et al. (2001) and to Eq. (5).
