WebTo determine the CRLB, we need to calculate the Fisher information of the model. I(θ) = −E ∂2 ∂θ2 logf(y; θ) = n σ2 (4) According to Equation 3, we have Var bθ MLE(Y) > 1 I(θ) = σ2 n. (5) And the variance of the MLE is Var bθ MLE(Y) = Var 1 n Xn k=1 Yk! = σ2 n. (6) So CRLB equality is achieved, thus the MLE is eﬃcient. 1.3 ...
