| 摘 要： | 本文探讨了曲线拟合模型选择的评价标准。主要从两方面来评价拟合质量,一方面是要使得数据拟合误差要尽量的小,另一方面要保证曲线的线形形状最佳,由此提出了新的评价准则,并通过实验验证了此评价标准的可行性。

| Abstract: | This paper discussed the evaluation criteria of curve fitting model selection.The fitting quality can be evaluated from two aspects.On the one hand,making the error of fitting the data is as small as possible.On the other hand,ensuring that linear shape of the curve is best.Some new evaluation criteria were proposed.Experiments proved the feasibility of these evaluation criteria. |
