10.2 For the sample in problem 10.1, consider another estimator of u (call it ê) that is defined as follows: ( 10.1 Suppose that we have a simple random sample of size 3 from a population with mean w. Our estimator of u is ê, defined as follows: When sampling from a nonnormal population, there may be unbiased es- timators of u that are more efficient than X. These estimators, however, would be nonlinear functions of the Xi's; that is,...

4. Let Yi, ½, . . . , Yn be a random sample from some pdf/pmf f(y; θ)·Let W be a point estimator h(y, Y2, . . . , Yn) for θ. The bias of W as a point estimator for θ is defined as W Blase(W) = E(W)- The mean square error of W is defined as MSEe(W) = E(W-0)2 (a) Using properties of expected values, and the definition of variance from PSTAT 120A/B, show that MSEe(W) = Vare(W)...
