介绍了自回归移动平均模型ARIMA(p,d,q)的原理和建模方法。根据田东县近年来年降雨量特征,建立了ARIMA(1,1,12)预测模型进行分析预测,并与灰色预测模型GM(1,1)的预测结果进行对比,对比的结果是ARIMA模型的预测精度比灰色预测模型的精度明显提高。
介紹瞭自迴歸移動平均模型ARIMA(p,d,q)的原理和建模方法。根據田東縣近年來年降雨量特徵,建立瞭ARIMA(1,1,12)預測模型進行分析預測,併與灰色預測模型GM(1,1)的預測結果進行對比,對比的結果是ARIMA模型的預測精度比灰色預測模型的精度明顯提高。

An introduction was made on the principle and modeling method of ARIMA(p,d,q)model. According to the annual precipitation characteristics of Tiandong County in recent years,ARIMA(1,1,12)model was set up for analysis and forecasting. The forecasting achievements were compared with that out of GM(1,1),showing that the precision of forecasting achievements out of ARIMA model is obviously higher than that out of GM.
