Scientific paper

Low-bias cold dark matter N-body simulations are analyzed using a scaling or multifractal formalism. It is shown that the multifractal formalism is a suitable tool to characterize and compare the clustering properties of N-body simulations and galaxy catalogs. Comparison of the clustering properties of the simulations with the results of a similar analysis of the 14.5 CfA catalog of galaxies shows that they are not very dissimilar.
