| 摘 要： | 线性模型最小二乘方估计的改进大致有两条途径：利用验前信息，如贝叶斯估计，改变估计形式，如特征根估计，主成分估计，本文提出ＢＬ（贝叶斯加特征根）估计和ＢＰ（贝叶斯加主成分）估计，实现两类途径的综合，有实用和理论价值。 |

| Abstract: | The paper propounds two new estimates,which are named BL estimate(Bayesian estimate combined with Latent root estimate)and BP estimate(Bayesian estimate combined with Principal components estimate).They not only use a priori information but also change calculative formulas. They are very efficienf when Bayesian estimate is still unsteady. |
| Keywords: | Linear models The least square estimate The Bayesian estimate Latent root estimate Principal components estimate BL estimate BP estimate Residual sum of squares(RSS) Mean square error(MSE) |
