Following a Migdal-Kadanoff-type bond moving procedure, the authors derive the renormalisation-group equations for the characteristic function of the full probability distribution of resistance (conductance) of a three-dimensional disordered system. The resulting recursion relations for the first two cumulants, κ1 the mean resistance and κ2, the mean-square deviation of resistance exhibit a mobility edge dominated by large dispersion, i.e. κ2½ /κ1 ≈ 1, suggesting inadequacy of the one-parameter scaling ansatz.
