... Often the posterior mean has lower MSE than the MLE for portions of the parameter space, so its a worthwhile estimator to consider and compare to the MLE. The posterior mean is consistent, asymptotically unbiased (meaning the bias tends to 0 as the sample size increases), and the asymptotic effi ...

... 14. An environmentalist group monitors the temperature rise in the water 50 yards downstream from a nuclear power station. Federal regulations permit a rise in temperature of 3.0°F. They collect 16 water samples and obtain a mean rise of 3.2°F with a standard deviation of 1.0°F. Does this show that ...
