  We present a self-consistent nonparametric model of the cosmic velocity field
based on the spatial distribution of IRAS galaxies in the recently completed
all-sky PSC$z$ redshift survey. The most streaking feature of the PSCz model
velocity field is a coherent large-scale streaming motion along the Perseus
Pisces, Local Supercluster, Great Attractor and Shapley Concentration baseline,
with no evidence for a backinfall into the Great Attractor region. A likelihood
analysis has been performed to measure $\beta$. We have obtained $\beta
=0.6^{+0.22}_{-0.15}$ (1-$\sigma$), in agreement with other recent
determinations.
