"Web1 Neyman-Fisher Factorization Theorem Theorem 2. The statistic T is suﬃcient for θ if and only if functions g and h can be found such that f X(x θ) = h(x)g(θ,T(x)) (2) 1. The central idea in proving this theorem can be found in the case of discrete random variables. Proof. Because T is a function of x, " - Fisher theorem
