摘要
为了科学预测黄金的价格行情,构建信息修正GM(1,1)模型来模拟其价格走势。首先对2011年国内黄金价格(Au9999)进行分析,选出波动较大的少量数据,再用信息修正GM(1,1)模型进行动态预测,最后将模拟结果与传统的GM(1,1)模型进行误差分析,并将预测结果与2012年1月、2月数据进行对比分析。结果表明信息修正GM(1,1)模型能减少随机扰动和驱动因素,其模拟和预测的精度较高,结果可靠。
In order to make the scientific prediction on gold price, the information revision GM(1,1) model is constructed to simulate the price trend. Firstly, the domestic gold (Au9999) price in 2011 is analyzed and a few data which have great fluctuation are selected. Secondly, the information revision GM(1,1) model is established to simu- late the gold price and predict the trend. Finally, the error comparative analysis is made with the traditional GM(1, 1) model, and the prediction results are compared with the data of January and February in 2012. The results show that the information revision GM(1,1) model can reduce the factors of random disturbance, the simulation and pre- diction accuracy are relatively high, and the analysis results are reliable.
