Using a new, highly accurate, method of analytic continuation, we provide the first quantitatively correct calculation of the resistivity and thermal conductivity of dilute spin-1/2 magnetic (Anderson and Kondo) alloys over the {ital entire} range of interest {ital T}{much lt}{ital T}{sub {ital K}} to {ital T}{much gt}{ital T}{sub {ital K}}. We find that our results are consistent with previous approximate theories in their regions of applicability. Our results are the first calculation of transport for any strongly correlated electronic many-body system obtained by direct analytic continuation of Monte Carlo data.
