| 摘 要： | 比较了不同的几种岭参数选择方法的应用效果，结果表明，几种方法中没有一种方法被认为是优于其它的方法。但在均方误差准则下．几种岭参数选择方法所获得的估计都改进了设计阵呈病态时的最小二乘估计。

| Abstract: | In this paper the situations of different ridge estimates were appliedly compared with one another from a practical point of view. The results demorstrated that on one method is superior to other ones. But all the procedures of biased estimating improved the least square estimates in various degrees under the criterion of MSE when the design matrix was ill conditioned. |
