·Minimum sample size:A minimum of 8 megabytes (MB) of data, or the size of the table if smaller, are now sampled during statistics gathering. ·Increased limit on number of statistics:The number of column statistics objects allowed per table has been increased to 2,000. An additional 249...
then \hat{\theta}^{*} is a Uniformly Minimum Variance Unbiased Estimator. 可以证明UMVUE如果存在的话,那一定满足唯一性。 Harald Cramér和C. R. Rao两位大师推导出了unbiased estimator方差的下界,这个下界也称为Cramér–Rao lower bound (C-R lower bound)。 从Cramér–Rao Inequality里面可以看出如果我们...

Let Xn and X 1 be the largest and smallest order statistics, respectively, of a random sample of size n. Quite generally, Xn and X 1 are approximately independent for n sufficiently large. Minimum n for attaining at least specified levels of independence are developed. Level of independence ...
