对称熵损失下工序能力指数C_p的估计

Estimation for the Exponent C_p of Process Capability under Symmetric Entropy Loss Function

研究工序能力指数在对称熵损失函数下的最小风险同变估计（MRE）和Bayes估计，给出MRE估计的精确形式，并对置信度为1-α的区问估计给出临界值，同时，证明Bayes估计是可容许的．

The present paper deals with the minimum risk equivariant estimator (MRE) and Byaes estimator of the exponent C. of process capability under symmetric entropy loss function, gives MRE's exact form and the confidence limit at confidence level 1-α, and at the same time, it proves that the Bayes estimator is admissible.
