iid = 1. Data y = {41, ..., yn} are observed where y; Gamma(4,K), with ß > 0. (a) Derive a Method of Moments estimator Bum for B, based on the first moment of f(y). [3] (b) Is your estimator biased? If so, what is the bias? [3] (c) What is the variance of your estimator? [4] (d) Write down the log-likelihood function e(Bly). [3] (e) Derive the score function l'(B|y). [3] (f) Derive the observed Fisher Information I(B). [3] (g) Derive the expected Fisher Information E[I (B)). [4] (h) Hence find the Maximum Likelihood Estimator BMLE for B [3] (i) Prove that BMLE is the Minimum Variance Unbiased Estimator. [5] [Total 31 marks]
