摘要
本文讨论了多元线性回归模型设计阵病态的诊断;岭回归系数的计算;岭参数的选择原则及变量筛选原则。编制了岭回归分析的BASIC程序,通过农业应用实例说明了程序的使用方法和岭回归分析方法。
The diagnosis of ill-conditioned design matrix, calculation of ridge regression coefficients and principles of selecting ridge parameters and variables were studied, based which a BASIC program of ridge regression analysis was worked out. Taking wheat as an example, the application of the program to farming was illustrated.
