摘要
本文运用时间序列建模方法对内蒙古第三产业增加值进行了分析和研究,首先通过对第三产业增加值序列的平稳化处理,然后运用ARMA方法进行建模,最终确立了ARIMA疏系数模型。经过检验,模型预测效果良好,可用于对未来的预测。
This paper analyses and studies tertiary industry increased value of Inner Mongolia with the method of time-series model.First of all,the paper analyzes the sequence of Tertiary Industry Increased Value through the method of smooth processing.Second,the paper use methods of ARMA modeling.Finally,the paper establishes the ARIMA Sparse Coefficient Model.After testing,The model works well and may forecast the future.
