2. Let X1, X2, ...,Xbe i.i.d. Poisson with parameter .. (a) Find the maximum likelihood estimator of . Is the estimator minimum variance unbi- ased? (b) Derive the asymptotic (large-sample) distribution of the maximum likelihood estimator. (c) Suppose we are interested in the probability of a zero: Q = P(Xi = 0) = exp(-). Find the maximum likelihood estimator of O and its asymptotic distribution.
Instructions: For each of the following distributions, compute the maximum likelihood estimator based on n i.d. observations X····, Xn and the Fisher information, if defined. If it is not, enter DNE in each applicable input box. which means that each X1 has density exp (-( 1)2 202 Hint: Keep in mind that we consider σ2 as the parameter, not σ . You may want to write τ-σ2 in your computation. (Enter barx_n for the sample average Xn and bar(X_n 2)...
