季节性数据的横断面建模方法

本文提出了一种对季节性数据建立数学模型的新方法──横断面方法．其思想是，把一个季节性时间序列划分成为数相当于一个季节周期长度的若干个子序列，在这些子序列中已完全消除了季节性因素，然后对这些子序列分别建立形式各异的数学模型，最后再把这些子序列的数学模型综合起来就得到了对原始序列的数学模型．

Section Modelling Method for Seasonal Data

In thispaper, a new method, called sectiong method,is developed for the modelling for seasonal data, The methods idea is that by sectioning the seasonal time series data into some sub-series data, the number of which is equal to the length of the seasonal period and in which seasonal factors are completely deleted, various kinds of models are built for each of these sub-series and then a model is obtained for the original series by linking all the sub-series models.
