| 摘 要： | 组合预测是利用各种预测模型所包含的独立有用预测信息对事物未来发展趋势进行预计、估测的过程。本文采用灰色系统理论中的关联分析方法,提出以参与组合的单个预测模型与被预测对象的关联系数和关联度为依据,确定变权重的组合预测模型方法。通过单项运动成绩的预测实例,显示了基于灰关联变权的组合预测方法是一种比单一预测方法更能收到较好预测效果的佳法。

| Abstract: | Combined forecasting using several forecasting model that embody alone information is process for a thing future development trend carry on forecasting. The paper us-ing correlation method of the system theory,based on Correlation coefficient and correlation degree of the single model by forecasting object, defined the Variable weight of combined forecasting. The real example of the sports result forecasting shows based on grey correlation variable weight combined forecasting has high fitting accuracy than ordinary single model. |
