| 摘 要： | 提出一种基于灰色关联度和GM(1,2)迟滞模型的组合预测方法.首先,利用数据建立不同迟滞时间的GM(1,2)模型,其次运用不同迟滞因子变量与单个行为变量的不同关联度确定权值,建立组合模型,进而利用组合模型进行数据的预测.用该方法,利用社会固定资产投资对我国第二产业进行预测,其模型预测精度较高,表明本文所提出的预测方法是有效的.

| Abstract: | This paper has put forward the combined forecasting based on grey correlation fixed weight and GM(1,2) time-lag model.First,GM(1,2) with different time-lags should be established.Second,the degree of grey incidence between behavioral variables and factor variables with different time-lags will be worked out.The degree of grey incidence weight is ascertained by the degree of grey incidence.Third,combined forecasting model is completed.This method is applied to predict the secondary industry and total investment in fixed assets in the country.The results show the method is effective. |
