We investigate the behaviour of galaxy clustering on large scales using PSCz catalogue. In particular, we ask whether there is any evidence large-scale fractal in this find correlation dimension survey varies with scale, consistent other analyses. For example, our results small and intermediate are those obtained from QDOT sample, but larger sample allows us to extend analysis out much scales. firm that becomes homogeneous at scales; D2=2.992±0.003 for r>30 h−1 Mpc. This provides strong favour a universe obeys cosmological principle.
