Question: Differentiate the gamma moment-generating function to verify the formulas for E(Y) and Var(Y) given in Theorem 4.6.3. Var(Y) = E(Y2)-[E(Y)12 r (r + 1)/2--(r/A)2 r

Differentiate the gamma moment-generating function to verify the formulas for E(Y) and Var(Y) given in Theorem 4.6.3.

Var(Y) = E(Y2)-[E(Y)12 r (r + 1)/2--(r/A)2 r

Var(Y) = E(Y2)-[E(Y)12 r (r + 1)/2--(r/A)2 r
