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 first approach focuses on power spectrum analysis techniques using a signal representation approach such as Wavelets to elaborate on the differences in classification results. Time series data are widely seen in analytics. An ideal method would allow different window sizes depending on the scales that one is interested in. WMTSA: wavelet methods for time series analysis. Some examples are stock indexes/prices, currency exchange rates and electrocardiogram (ECG). Title, Wavelet Methods for Financial Time Series Analysis. Insightful has released the following time series packages via CSAN at http://csan.insightful.com: FRACTAL: stochastic fractal time series and nonlinear modeling. The second approach focuses on . As EEMD is a time–space analysis method, the added white noise is averaged out with sufficient number of trials; the only persistent part that survives the averaging process is the component of the signal (original data), which is then treated as the true and more physical meaningful This requirement reflects the evolution of time series analysis from the Fourier transform, to the windowed Fourier transform (Gabor 1946) and on to wavelet analysis (Daubechies 1992). No, but of course there are examples where weather and climate data time series both from observations and from climate models have been analyzed with wavelets.

Wavelet analysis theory is one of the topics widely discussed and studied in the communities of science and engineering currently.
