Abstract
We calculate the distribution of eigenfunction amplitudes and the variance of the ``inverse participation ratio'' (IPR) in disordered metallic samples. A relation is established between the distribution function of IPR and that of ``level velocities'' -- parametric derivatives of energy levels with respect to a random perturbation.Comment: REVTEX, 7 pageKeywords
