摘要
利用离散GM(1,1)模型,新息GM(1,1)模型以及复合函数预测模型建立了一类变权重组合预测模型.并将该组合预测模型应用于喀什地区GDP预测,建立了喀什地区GDP的变权重GM(1,1)组合预测模型.计算结果表明变权GM(1,1)组合预测模型在时间序列数据的预测中具有一定的优势.
In view of the limitations in the single forecasting model, the new weight change- able combination forecast method was put forward according to the discrete GM（1,1） model and new information GM （1, 1） model and compound functions forecast model. And then, this weight changeable combination forecast method was applied to GDP prediction of Kashi region. The forecast results indicates that the precision of weight changeable combination forecast method is higher than single forecast models. So this new method is feasible and effective.
