增长曲线模型中回归参数阵的线性有偏估计类

In response to some perceived deficiency with the BLUE of the regression parameter matri xin the growth curve model,this paper proposes a class of linerar biased estimators,which is called a class of universal ridge ones(URE).based on the recent deveopment theory of biased estimation on the classical regression model.By appropriate choices of the included biased parameters,many interesting and practical linear biased estimators may be obtained.Some important properties are also discussed.With the UR estimators,the estimation methods used in the growth curve model will be greatly ennriched.
