WebFirst note that the gamma distribution is closed under scalar multiplication. So if X is gamma then a X is gamma, a > 0. Let u, v, w be positive constants then if u v / w = 1. F = A B / C = u v / w A B / C = ( u A) ( v B) / ( w C) So you need to put constraints in order to solve this problem uniquely. Share Cite Follow edited Sep 28, 2012 at 14:30 WebLand Intern.
