【摘要】 文章将组合模型引入黑龙江省粮食产量预测。通过分析确定了构成组合模型的三个单项模型:改进的指数平滑模型、Cobb-Dauglas生产函数模型和灰色马尔可夫模型;并确定了组合模型权重的方法,通过实证验证了其可行性,证明组合模型可以充分的利用各种预测方法所提供的信息,达到提高预测精度的效果。更多还原

【Abstract】 The introduction of the combined model predicted grain yield in Heilongjiang Province.Determined by analyzing the composition of the three individual model portfolio model: Improved exponential smoothing model,Cobb-Dauglas production function model and the Grey-Markov model;and determine the weight of the combined model approach,through empirical verification of its feasibility,that combined model can take full advantage of prediction methods to provide information to improve forecast accuracy results.更多还原
