文摘:针对线性加权回归模型，从统计诊断的角度分析了协方差阵扰动的影响度量和回归系数的估计效率，并给出了2种效率的下界 - Based on the least squares and biased estimation especially ridge estimation , a new estimation , that is , generalized ridge estimation is put forward through studies on restriction of the parameter . model ' s prediction being considered , comparison of superiority of optimal and classical predictions with respect to the ridge estimation is showed . regression diagnoses especially distance for principal components estimation is discussed
论文基于最小二乘估计及有偏估计特别是岭估计，对参数的约束条件做了进一步研究，并提出一种新型估计即广义岭型估计；对模型的点预测问题进行深入探索，得出一种基于岭估计关于经典预测和最优预测的最优性判别条件；也对回归诊断特别是基于主成分估计的距离进行了深入探讨。
