WebI ask because in statistical physics a cumulant generating function, the logarithm of a moment generating function, is an additive quantity that characterizes a physical system. If you think of energy as a random variable, then it's cumulant generating function has a very intuitive interpretation as the spread of energy throughout a system. Webwhere the first two cumulants are κ 1 = E ( X) and κ 2 = Var ( X). In your case, C X ( t) = 2 t, hence κ 1 = 2 and κ 2 = 0, wherefrom it is easy to conclude that X = 2 a.s. Note that the 'bare-hands' proof given @Davide has something close to this approach with the cumulant generating function.
