exercise: Determine and prove the expressions for E (u), Var (u), Mu (t), I need the three expressions for F non-central demonstrated in detail thanks Non-central F distribution Suppose u random variables that have a non-central chi-square distribution, , and sea v central chi square random variable Am: ', with u and v independent. Then F(n.m.x) is the non-central distribution F with non-centrality parameter A. exercise: Theorem 7 If u ~ F (n, m, A), then e-dak ninthmamp (ntm + k) utk-1 f(u) = K = 1 k! (n + mu) 1 E(u) = Var(u) = Mu(t) =
