Numerical and analytical details are presented on the newly discovered superscaling property of the energy spacing distribution in the three dimensional Anderson model. PACS: 71.30.+h, 72.12.Rn, 05.40.+j .
In this paper, we estimate probability { } Y X P < when X and Y are two independent random variables from Dagum distribution. We obtain maximum likelihood estimator and its asymptotic distribution. We also perform a simulation study.
