摘要
我们基于与经常的术语预报的最佳的加权的 combinational 建议一个模型，没有经常的术语，象模型和相应模型的一种关系一样给重量和平均错误的公式，并且比较这些模型。最后，一个例子被给，它证明恰当的精确被提高了。
We propose a model based on the optimal weighted combinational forecasting with constant terms, give formulae of the weights and the average errors as well as a relation of the model and the corresponding model without constant terms, and compare these models. Finally an example was given, which showed that the fitting precision has been enhanced.
