| Abstract: | Through analyzing the characteristics of wavelet theory and grey model,the grey forecast model based on wavelet analysis is proposed.By the wavelet transform,the deformation sequence is decomposed and then each subsequence is forecasted with grey model.After reconstruction,the forecasted results are obtained.At the same time,the results are compared with that forecasted only by use of grey model.The research shows that the new forecasting method can improve forecast precision. |
