摘要
对于线性回归模型,本文提出了回归系数的一种单参数主成分估计,证明了它的可容许性、抗干扰性、有效性等主要性质。
In this article, we propose a single-parametric principal component regression estimator for unknown coefficients in a linear regression model.Some optimalties, sucb as admissibility, numerical stability and relative efficiency, are also proved.
