Question

Consider a non-negative discrete random variable Y âˆˆ â„• governed by the following probability mass function: Pr(Y = y) = (Î»^y) * (e^(-Î»)) / y!, where Î» > 0. This probability distribution is a member of the Exponential family. Answer the following questions: [Total 40 marks] (a) Express the mathematical link between probability distribution (1) and the Poisson distribution. (5 marks) (b) Convert the probability mass function (1) into an exponential family form and specify the components of the distribution: Î», a(Î»), b(Î»), and c(y, Î»). (7 marks) (c) Derive E[Y] in terms of Î» and a. Also, derive Var(Y) in terms of Î», a, and E[Y]. You can leave the answer as an infinite sum. (8 marks) (d) Specify and explain a procedure to find the MLE (Maximum Likelihood Estimation) for independently identically distributed observations: Yâ‚, Yâ‚‚, ..., Yâ‚™, expressing the required formulae at each step. (20 marks)
