【摘要】 该文尝试应用灰色趋势~逐步回归周期组合模型于韩江潮安站长期水文预报中,并与单纯用灰色GM(1,1)模型及单纯用逐步回归周期分析预测模型作比较,结果表明,该组合模型取得更优的预测效果。更多还原

【Abstract】 Base on The Grey-Stepwise Regression Period Combinatorial Model,Chaoan station in Hanjiang basin prediction model is developed.The fitting result is more satisfactory than the GM(1,1) model and the Stepwise Regression Period Model.Though the accuracy of the actual forecasting is not so high than the fitting accuracy,the combinatorial model is worth to be studied and improved.更多还原
