组合预测方法及其在粮食单产分析中的应用

An Application oF Combination Forecasting Method for the Analysis of Foodgrain Yields

介绍组合预测模型及最优权重的确定,并通过此方法对黑龙江省某农场粮食单产进行了预测,建立了组合预测模型。从预测结果上看,组合预测模型优于单一预测模型,使预测精度有一定的提高。

The forecasting model of combination and the best of distribution coefficient have been confirmed. This model has been applied to analyze foodgrain yields of a farm in Heilongjiang province. By the analysis results, the forecasting model of combination is superior than the forecasting model of singleness and the precision of forecasting is improved. [
