  Radial velocity surveys are examined in terms of eigenmode analysis within
the framework of CDM-like family of models. Rich surveys such as MARK III and
SFI, which consist of more than $10^{3}$ radial velocities, are found to have a
few tens of modes that are not noise dominated. Poor surveys, which have only a
few tens of radial velocities, are noise dominated across the eigenmode
spectrum. In particular, the bulk velocity of such surveys has been found to be
dominated by the more noisy modes. The MARK III and SFI are well fitted by a
tilted flat CDM model found by a maximum likelihood analysis and a $\chi^{2}$
statistics . However, a mode-by-mode inspection shows that a substantial
fraction of the modes lie outside the $90% $ confidence level. This implies
that although globally the CDM-like family of models seems to be consistent
with radial velocity surveys, in detail it does not. This might indicate a need
for a revised power spectrum or for some non-trivial biasing scheme.
