You have a random sample with n iid observations from the following density: Le- if x >0 f(x) = otherwise where the parameter r > 0. For this distribution, we have: 4 – T E[X]: var[X] = 2 (a) Show that the maximum likelihood estimator of r is: n 1 ÎMLE 2n i=1 (b) Is îMLE an unbiased estimator for r? Justify your answer. (c) Find the Fisher information and construct a large-sample 95% confidence interval for r.
