  The phase diagram of correlated, disordered electron systems is calculated
within dynamical mean-field theory using the H\"older mean local density of
states. A critical disorder strength is determined in the
Anderson-Falicov-Kimball model and the arithmetically and the geometrically
averages are found to be just particular means used respectively to detect or
not the Anderson localization. Correlated metal, Mott insulator and Anderson
insulator phases, as well as coexistence and crossover regimes are analyzed in
this new perspective.
