Name: 4. Let X1, X2, ..., Xn be a random sample from the Poisson distribution with parameter ?1. The probability mass function is P(X = x) = (e^-?1 * ?1^x) / x!. Note that E(X) = Var(X) = ?1. a) (5 marks) The maximum likelihood estimator of ?1 is the sample mean (i.e. ??1 = X?). Show that ??1 is the MVUE (minimum variance unbiased estimator). b) (1 marks) Assuming n is large, justify that the approximate distribution of ??1 is N(?1, ?1/n).
