The method of combining wavelet transform and chaos theory is used to forecast the stock market, that is, first to perform wavelet decomposition on the time series of the stock index, and then to perform chaotic prediction on the high and low frequency parts obtained by the decomposition, and then to reconstruct the prediction result by wavelet. The prediction result of the original time series. On this basis, wavelet and chaos theory is used to propose a method for further improving the prediction accuracy, that is, the high-frequency portion is further subjected to wavelet decomposition, chaotic prediction, and wavelet reconstruction to improve the prediction accuracy of the high-frequency portion, thereby improving the original time series. Prediction accuracy.
