Let x poi m and let theta px 0 e-m. compare the mses of, Ask an Expert

Statistics

Let m = mean
Let X ~ POI (m), and let theta = P[X = 0] = e^(-m).

a) Is theta(hat) = e^(-X) an unbiased estimator of theta?

b) Show that theta~ = u(X) is an unbiased estimator of theta, where u(0) = 1 and u(x) = 0 if x =1,2, ...

c) Compare the MSEs of theta(hat) and theta~ for estimating theta = e^(-m) when m=1 and m=2
