WebMay 27, 2024 · And the expectation will be computed as: E [ ∂ ∂ y log [ f ( x, y)]] = E [ t] = ∫ − ∞ ∞ t g ( t) d t So with this second method you differentiate with d t and not d X. And the derivation on Wikipedia is using method 1, where you should not interpret part of the integrand as the density of T but as the density of x. WebDerivatives of all orders exist at t = 0. It is okay to interchange differentiation and summation. That said, we can now work on the gory details of the proof: Proof: Evaluating for mean and variance Watch on Example 9-2 Use the moment-generating function for a binomial random variable X: M ( t) = [ ( 1 − p) + p e t] n
