| 摘 要： | 在分析灰色模型与回归模型特点基础上提出了灰色回归模型,并以最小二乘法确定了两单一模型权重系数的分配。结果表明：灰色回归预测模型在最大、最小误差及平均误差这三项指标中明显优于两单一模型。因此,灰色回归模型能显著提高预测精度,可作为农业用水量预测的一种有效工具。

| Abstract: | The model of gray regression was put forward on the basis of analyzing the feature of gray model and regression model,and the distribution of two single model weight coefficient was definited by the method of least square.The outcome showed that prediction model of gray regression overmatched two single model in the three indexes of maximum error,least error and average error.Therefore,the model of gray regression can raise precision of prediction significantly,and it can be considered as an effective tool ... |
