摘要
对曲线拟合度分析法的基本原理进行了介绍,阐述了回归预测中引入曲线拟合度分析法的作用,并选取杭州市"十一五"期间货运量与生产总值数据构建若干回归预测模型,通过曲线拟合度比较分析,优化了预测模型选择.实验结果表明该方法所获得的模型预测结果相对接近于实际.
In the paper,the basic principle of the curve fitting degree analysis method was introduced,and the function of the method for regression forecast was discussed.The data of freight and GDP in Hangzhou during ＂Eleventh Five-Year＂ period was used to construct several regression models,and the method was used to optimize the model.The results indicated that the prediction data of the obtained model were relatively close to that of the actual trend.
