- Wavelet Methods for Time Series Analysis, by Percival and Walden: standard theoretical text on wavelets. Details of scaling and translation of the Morlet wavelet with an interactive Demonstration. Frequency analysis and decompositions (Fourier-/Cosine-/Wavelet transformation) for example for forecasting or decomposition of time series; Machine learning and data mining, for example k-means clustering, decision trees, classification, feature selection; Multivariate analysis, correlation; Projections, prediction, future prospects But in order to derive ideas and guidance for future decisions, higher sophisticated methods are required than just sum/group by. It should be remarked that the definition of functional connections in previous FW analysis methods , – is basically based on the Pearson's correlation approach (two signals are correlated if we can predict the variations of one as a function of the other).

If the value of In this paper, we develop a method to construct a new type of FW from regional fMRI time series, in which PS degree ,  between two regional fMRI time series is taken as the functional connection strength. The complexity of the system is expressed by several parameters of nonlinear dynamics, such as embedding dimension or false nearest neighbors, and the method of delay coordinates is applied to the time series. Colored noise and computational inference in neurophysiological (fMRI) time series analysis: resampling methods in time and wavelet domains. When applied to time-series data, wavelet analysis involves a transform from the given one-dimensional time series to a two-dimensional time-frequency image. We also fit Finally, we find that a series of damped random walk models provides a good fit to the 10Be data with a fixed characteristic time scale of 1000 years, which is roughly consistent with the quasi-periods found by the Fourier and wavelet analyses.
