混合系数线性模型的几乎无偏岭估计
ALMOST UNBIASED RIDGE ESTIMATOR FOR A MIXED-EFFECT COEFFICIENT LINEAR MODEL
摘要
Abstract
In the paper, we consider a mixed-effect coefficient linear model with the repeatedly measured data. Using the ridge method, the almost unbiased ridge estimator (AURE) of the model are given. It is proved that the AURE excels the ridge estimator (RE) under a mean square error (MSE), and the optimal value for the biased parameter is established by minimum MSE.关键词
