| Abstract: | The inequality of arithmetic mean and harmonic mean is generalized to the positive definite matrix. With this inequality, we get the optimal properties of Bayes unbiased estimates. |
| |
| Keywords: | positive definite matrix conditional expectation inequality of arithmetic mean Bayes estimator unbiased estimate. |
