时间序列分析在粮食产量预测中的应用

The Applications of Time Series Analysis in Grain Yield Prediction

在预测粮食产量中可以应用时间序列分析.叙述了时间序列模型的辨识、预测及建模过程,利用Matlab系统辨识工具箱对时间序列进行数据预处理,相关分析,ARMA模型参数估计,并对2010年的粮食产量进行了预测.

This paper describes the identification,forecasting and modeling process of time series models.By using of Matlab system identification toolbox,we discuss data pre-processing,correlation analysis and ARMA model parameter estimation in time series,and did a prediction of grain yield in 2010.
