The standard error of estimate, on the other hand, measures the variability, or scatter, of the observed values around the regression line.
而估计值的平均误差，却是度量观察值围绕着回归直线的变化程度或分散程度。
The investigation object of this paper is the standard canonical form. In order to the mean square error, I analyze the existence and choiceness of ridge regression K in some spectrum.
本文以多元线性回归模型的典则形式为研究对象，从减小均方误差的角度出发，在一定的范围内分析了岭参数K 的存在性和岭估计的优良性。
