Pitman准则的若干新发展
Some Recent Developments in Pitman’s Measure
-
摘要: Pitman准则是比较两个估计优劣的一种标准。本文综述了在这一方向上近年来若干方面的新结果,这包括正态总体参数估计和一般线性估计在Pitman准则下的比较,协方差改进估计的Pitman优良性,以及Bayes观点下的Pitman准则。Abstract: The paper presents a survey of some recent developments in Pitman’s measures of closeness. The titles of each section are in turn: the definition and some general results;parameter estimation of normal population; linear estimators under Pitman’s measure of closeness; Pitman optimality of covariance-adjusted estimator and Pitman’s measure of closeness from the Bayesian point of view.
