We determine the spatial distribution function of galaxies from a wide range of samples in the Two Micron All Sky Survey (2MASS). The results agree very well with the form of the distribution predicted by the theory of cosmological gravitational many-body galaxy clustering. On large scales we find a value of the clustering parameter b=0.867±0.026, in agreement with 0.83±0.05 found previously for the Pisces-Perseus Supercluster. We measure b(θ) as a function of scale, since this is a powerful test of the applicability of computer simulations. The results suggest that when galaxies clustered they were usually surrounded by individual rather than communal halos.
