摘要
在简要介绍时间序列模型的基础上,使用人民币/美元的日汇率值进行实证研究,建立相应的ARIMA模型和EGARCH模型并进行预测和评价.研究结果表明,EGARCH模型的预测结果较ARIMA模型理想,适合描述人民币/美元汇率的变动趋势.
Based on the application of time series model, some empirical studies into the daily data on RMB exchange rate are made. ARIMA and EGARCH models are built to simulate and forecast the pattern of the rate. The conclusion is that the predicted result of EGARCH model is more fitted than that of ARIMA model and the EGARCH model can describe the dynamic characteristics of RMB exchange rate more oppropriately.
