评价回归模型拟合效果的数量化方法

Quantitative Methods for Evaluating the Performance of Regression Models

回归模型模拟的效果直接影响其预测结果的精确性。针对残差分析法检验模型拟合效果的局限性 ,采用数量化方法进行检验 ,不仅综合分析了模拟效果 ,而且可以直接比较模型间的拟合效果 。

The simulation results of regression models have direct effect on the precision of prediction. In order to get over the limitation of evaluating model performance with residual analysis, quantitative methods of evaluating the performance were used, which not only analyzed simulated effects, but directly compared the performance among models and adequate foundations, it also has been provided for establishment of a new model with high performance.
