Problem 1. Let A, and 62 be two unbiased estimators of the positive parameter d. (1) Suppose the efficiency of 61 relative to 02 is given by efford, (0) = 1+0, 0>0. Which estimator would you prefer? (2) Suppose the efficiency of 6 relative to 62 is given by eff on,62 (0) = exp(-0), 0>0. Which estimator would you prefer in this case
