  We present numerical results for the statistics of $z$'s ($z$'s are defined
as logarithm of eigenvalues of the transfermatrix $T^\dag T$) at the critical
points of Anderson transition in 3D and 4D. The change of the density of $z$
due to the crossover from the metallic to the localized regime is described.
Linear behavior $\rho(z)= z$ at the critical point in 3D is proven and
discussed. In the insulating regime, the universal form of $\rho$ has been
found.
