             abstract = "Almost all galaxies have massive central black holes in their 
                         centers with masses typically ranging from ~105 to ~109 M. 
                         However, the origin and evolution of these objects and their 
                         connection with the hosting galaxies are not completely understood 
                         yet. In this work we analyze the mass accretion rate of 
                         supermassive black holes (SMBH's) and the mean Eddington ratio 
                         (MER) of type 1 AGN using data from the Sloan Sky Survey. For this 
                         purpose we improve the method for constructing the subsample of 
                         SMBH, taking into account the survey flux limit and the bias of 
                         the sample. It was observed that the mean bolometric luminosity of 
                         the active black holes can be represented by a function composed 
                         by a power law in mass and a like-Schechter function in redshift. 
                         Our results also show that both the mean Eddington ratio and the 
                         mass accretion rate are proportional to this function. © 2014
