Forecasting RMB Exchange Rate Based on a Nonlinear Combination Model of ARFIMA, SVM, and BPNN

Figure 4

Comparison of the RMB/USD predicted values by the NCM-f model (ARFIMA, SVM, and BPNN) and the actual values and the corresponding errors. The absolute error is defined as the difference between the forecasting value and the actual value, and the relative error is defined as the ratio between the absolute error and the actual value.
