| Abstract: | Wavelet was introduced to the I.MS model to estimate and test the long memory of volatility, and a pseudo-maximum likelihood estimation method based on wavelet transform long memory of volatility and the test method of long memory volatility were proposed. The size of long memory effects for different ex- change rate volatility sequence was verified . The results show the existence of long memory effects for exchange rate fluctuations sequence. RMB plays an important part in the dollar exchange rate fluctuations sequence, which is influenced by historical information. |
