季节性交乘趋势模型建立的方法改进

Improvement in the method of season cross-multiplication trend model

首先用F检验法来确定季节性交乘趋势模型的周期 ,然后对建模过程中的初始值确定方法进行改进 ,从而得到更好的预测结果 .

We use F test method to define season cross-multiplication trend model's period and improve the method of defining initial value in the course of establishing the model. Better forecast results are obtained.
