WebThe change of variables u = ( 1 − w) v yields that f W ( w) is a constant factor C times w s − 1 − r times ( 1 − w) n + r − s. This also yields the value of the constant factor C since f W must integrate to 1. (Or, after the change of variables, one can recognize the integral over v from 0 to 1 as a Beta.)
