岭回归分析在土壤流失数学模型中的应用

Application of Ridge Regression Analysis in Making Mathematical Models for Soil Erosion

古典回归分析在林业生产和科研中被广泛应用,但很少考虑自变量各因子的相关问题.而自变量各因子相关又是经常的.本文注意到这一点,介绍了以缩小均方误差为目的的有偏估计方法——岭回归分析[3,4]及其在土壤流失数学模型中的应用.

Regression analysis is a method that is used to reseachrelationships among random variables. Classic regression analysis, which is widely used in forestry science research and production, omits the interrelation of facts with independent variables. So we adopted ridge regression analysis to reveal the interrelationships among facts of independent variables. This method is worthy of further use and study. We introduced this concept of ridge regression analysis to demonstrate its advantages, choice of x value and applications in making a mathematical model for soil erosion
