Abstract
In this letter I present results from a correlation analysis of three galaxy redshift catalogs: the SSRS2, the CfA2 and the PSCz. I will focus on the observation that the amplitude of the two-point correlation function rises if the depth of the sample is increased. There are two competing explanations for this observation: one in terms of a fractal scaling, the other based on luminosity segregation. I will show that there is strong evidence that the observed growth is due to a luminosity-dependent clustering of the galaxies.
