Abstract

Si considera il rapportotra due forme quadratiche di variabili normali indipendenti e la sua distribuzione sulla ipersfera unitaria. Viene poi ottenuta una decomposizione per forme quadratiche in termini di vettori aleatori di tipo sferico. Si ottengono infine le espressioni esatte per la densità di probabilità in alcuni casi particolari.
