摘要
对人民币/美元汇率建立无偏灰色马尔科夫预测模型,该模型是对GM(1,1)模型的改进.实证研究结果表明,该模型预测精度优于ARMA模型、GARCH(1,1)模型以及灰色马尔科夫模型的预测精度.
According to the characteristics of RMB/USD exchange rate,Gray Markov model is introduced.The results shows that the prediction accuracy is better than the ARMA model,GARCH(1,1) and the Grey Markov Model.
