Query: Deviations from Hierarchical Clustering in Real and Redshift Space   We discuss the effects of redshift--space distortions on the estimate of high
order galaxy correlation functions. We use both the Perseus--Pisces redshift
survey and the results of high--resolution N--body simulations to explore the
consequences of working in redshift space on the detection of deviations from
hierarchical clustering. Both for real and simulated data, significant
deviations from hierarchical clustering seem to be present in real space. Their
behaviour is coherent with that expected from an initially biased galaxy field,
once the displacement from the sites where galaxies formed, due to the
nonlinear gravitational evolution, is taken into account. The passage to
redshift space has the net effect of filtering out the higher powers required
to fit the distribution in real space. This magnifies the distortions operated
by nonlinear evolution on the initial distribution, erasing the residual narrow
scale range (2--5~$h^{-1}$Mpc) where deviations from hierarchical clustering
are still detectable in real space. We conclude that such deviations can hardly
be estimated using data in redshift space.
