In the time sequence the trend component and periodical component were considered to make the load forecasting model more coincident with the features of power loads. 同时，时间序列考虑了趋势分量和周期分量，使负荷预测模型更加符合电力负荷特性。
Considering the effects of the outside factor and the periodic change of the predictand, the multivariate mixed threshold regression model with periodic components is developed. 摘要在综合考虑预测对象的周期变化和前期外部因子的共同作用后，给出带有周期分量的多元混合门限回归模型。
