In this paper, multiwavelength chromatic luminosity at radio (logLR
), optical (logLO ), X-ray (logLX ), and γ -rays (logLγ ) for a sample of 442 Fermi blazars with known redshifts are collected from Fan et al. ( 2016 ), to study the correlations between the γ-rays and the low-energy bands using a multiple linear regression analysis. In this way, we can see which band is more important for the γ -ray emissions. Mutual correlation analysis is also used to discuss the correlations between the γ -ray and the low energy bands for the whole sample and subclasses. We come to following conclusions: The multiple linear correlation indicates that the γ -rays are correlated with the radio, optical and the X-ray emissions for the whole sample and the subclasses of flat spectrum radio quasars (FSRQs) and BL Lac objects (BL Lacs), the correlation between the γ -rays and the radio emissions is the strongest one.For BL Lacs, the optical emissions are more important than the X-rays for the γ -rays, while the X-ray emissions are more important than optical ones in FSRQs.The γ -ray emissions in HBL are from an synchrotron self-Compton, while those in FSRQs may be from external Compton and synchrotron self-Compton as well.
