生长曲线模型的几乎无偏岭估计
Almost Unbiased Ridge Estimators of Regression Coefficient in Growth Curve Model
摘要
Abstract
In this paper,the almost unbiased ridge estimator(AURR) of regression coefficients is considered in growth curve model.We show that the mean square error(MSE) of above estimate is less than MSE of ridge estimator(RR) estimate.In the meantime,a example to test our conclusion is used.关键词
