iid of f(y) 1. Data y = {41, ... , yn} are observed where y;" Gamma(4, ), with B > 0. , (a) Derive a Method of Moments estimator Bum for B, based on the first moment [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'(Bly). [3] (f) Derive the observed Fisher Information I(B). [3] (g) Derive the expected Fisher Information E[T(B)].
