- 摘要:
- 通过对2000年1月至2014年10月的中国西瓜月度批发价格数据进行分析,建立了基于时间序列的价格预测模型。结果表明:SARIMA模型和季节因子分离模型都能较好地模拟国内西瓜价格波动,而组合模型对单一模型的预测精度又有一定提高;在此基础上对2014年11月至2015年12月的西瓜月度批发价格进行了预测分析。
- Abstract:
- The paper established a price forecasting model based on time series through the analysis on monthly wholesale prices of watermelon in China from January 2000 to October 2014.The results indicated that both ARIMA models and seasonal factors separate models could simulate the watermelon price effectively,and the combined model had a higher precision of prediction than a single model.Then,the monthly wholesale price of watermelon from November 2014 to December 2015 was forecasted on the base of the combined model.
