补充资料：统计方法的效率
统计方法的效率
efnciency of a statistical procedure
用来把一特定类中的统计方法与最优方法作比较的概念.在数理统计中，统计方法的最优性概念通常是根据该方法的风险(函数)来表述，而风险又直接依赖于损失函数的选择.因此，可能出现这样的情况:同一统计方法在某种意义下是很有效的，甚至是最优的，而在另一种意义下的效率却较低. 统计方法的效率是一个不太明确的概念.在诸如统计假设检验、统计估计的特定的数理统计问题中，它有更明确的含义. M.C HR卿 Jl朋撰吴启光译陶波校统计方法的效率〔emcienCy of a sta由目侧目脚仪曰眠;冲加‘一m一战浦川”甲阅陌“]
