“efficient estimate”的概念、定义、翻译、参考文献-科学参考

单词	efficient estimate
释义	efficient estimate Encyclopedia 理学参数估计释 efficient estimate有效估计一致最小方差无偏估计是一种优良估计量，这里的方差到底有多小呢？克拉默-拉奥（Rao-Cramer）在1945～1946年给出了一个无偏估计的方差所不可逾越的下界，亦称克拉默-拉奥不等式或克拉默-拉奥下界，实际上有一些一致最小方差无偏估计未必能达到克拉默-拉奥下界。因此，我们把无偏估计的方差达到克拉默-拉奥下界的估计称之为有效估计。 Mathematics ＞数理统计＞样本·统计量＞释义 efficient estimate有效估计 efficient estimate有效估计^†
