Available time series prediction method is linear models such as AR and ARIMA, these models need people to determine the order and type, the subjective factor is relatively large and there is no way to nonlinear models for effective approximation. The first approach focuses on power spectrum analysis techniques using a signal representation approach such as Wavelets to elaborate on the differences in classification results. Wavelet analysis theory is one of the topics widely discussed and studied in the communities of science and engineering currently. We publish the guest blogs and these first reactions at the same time. Title, Wavelet Methods for Financial Time Series Analysis. This time we asked the invited experts to write a first reaction on the guest blogs of the others, describing their agreement and disagreement with it. Fig 3: Wavelet analysis of the stalagmite time series. Through the difference or logarithm transform, the Not only avoid to inherent defects of neural network, but also together with the local approximation of wavelet analysis. The normal reaction of the bureaucrat is to try and discredit the independent research by using the same techniques that we often see here. The WT has developed into an important tool for analysis of time series that contain non-stationary power at many different frequencies (such as the EEG signal), and it has proved to be a powerful feature extraction method [16]. The second approach focuses on .
