A statistical analysis of the angular projection of the large-scale stellar mass distribution, as obtained from the Sloan Digital Sky Survey (data release 7) with the stellar masses of galaxies, finds values of the clustering length $r_0$ and the power-law exponent $\gamma$ of the two-point correlation function that are larger than the standard values, on account of the presence of very massive galaxies. A multifractal cosmic-web model with a transition to homogeneity at about 10 Mpc/h is still good, but there is considerable uncertainty in both this scale and the correlation dimension.
