协方差改进法及其应用

Covariance Adjusted Approach and Its Application

协方差改进法是构造更好估计的一个有力工具．本文在系统讨论了这个方法及其重要性质基础上，综述了它在许多模型的参数估计中的应用．这包括半相依回归模型、线性回归模型和生长曲线模型．本文还提出了几个未解决的问题．

Covariance adjusted approach is a powerful tool for constructing a better estimator. After introducing the approach and some important properties, this paper provides a survey of its ap-plications to various statistical models, which include the seemingly regression model, the linear regression model and the growth curve models. Some open problems are also proposed
