Correlations between radio, optical emission lines, 2-10 keV luminosities and black hole masses have been investigated for a sample of neabry Seyfert galaxies showing a wide range of Eddington ratios (L/L(Edd) from 0.1 down to = 10^(-7)). Results will be discussed within theoretical models to verify if these Seyfert nuclei are simply a scaled-down version of luminous AGN or if different physical processes are responsible for their emission.
