23. Suppose X1, . . . ,Xn are i.i.d. Poisson variables with mean A and we are interested in estimating p = P).(Xe = 0) = e'J'. a) One estimator for p is the proportion of zeros in the sample, p" = #{i 5: n : Xi = U}. Find the limiting distribution for p). b) Another estimator would be the maximum likelihood estimator 13. Give a formula for 35 and determine the limiting distribution for x/ p). c) Find the asymptotic relative eiciency of 16 with respect to 13
