我国人口时间序列拟合模型的比较与选择
Comparison and Selection of the Fitting Models Based on the Time Series of China Population
【摘要】 通过对我国1990年至2007年共18年的人口数据进行实证分析,运用时间序列的三个不同模型,对我国人口的变化规律进行了拟合研究;并给出了反映各个模型拟合精度的AIC值和SBC值;最后,通过对所建模型的比较分析,对拟合模型的选择提出了相关建议.
【Abstract】 Evidence-Based Analysis on the data of China population from 1990 to 2007 and three different time series model are given,which have fitted the change regulation of China population.At the same time,values of AIC and SBC are showed for reflecting the precision of fitting.Finally,through comparison and analysis of exsiting models some advices are given to how to choose the model.
