... Point Estimation and its variance attains the Cramér–Rao bound. 12.4.2 Refer to Exercise 12.3.5 and investigate whether the Cramér–Rao bound is attained. 12.4.3 Refer to Exercise 12.3 .6 and investigate ... () ∈ [] = () ∈ [] By assuming the existence of an MLE, we have that the maximum at the left-hand side above is attained at an MLE ˆ θθ θθ θ. Then, clearly, the right-hand side attains i...
