The change of the density of $z$ due to the crossover from the metallic to the localized regime is described. Linear behavior $ρ(z)= z$ at the critical point in 3D is proven and discussed. In the insulating regime, the universal form of $ρ$ has been found.LATEX, 6 .eps figuresDisordered Systems and Neural Networkstext
