  Accepting validity of self-consistent theory of localization by Vollhardt and
Woelfle, we derive the relations of finite-size scaling for different
parameters characterizing the level statistics. The obtained results are
compared with the extensive numerical material for space dimensions d=2,3,4. On
the level of raw data, the results of numerical experiments are compatible with
the self-consistent theory, while the opposite statements of the original
papers are related with ambiguity of interpretation and existence of small
parameters of the Ginzburg number type.
