Spectrum continuation analysis — (SCA) is a generalization of the concept of Fourier series to non periodic functions of which only a fragment has been sampled in the time domain.Recall that a Fourier series is only suitable to the analysis of periodic (or finite domain)… … Wikipedia
Detrended fluctuation analysis — In stochastic processes, chaos theory and time series analysis, detrended fluctuation analysis (DFA) is a method for determining the statistical self affinity of a signal. It is useful for analysing time series that appear to be long memory… … Wikipedia
Detrended Correspondence Analysis — (DCA) is a multivariate statistical technique widely used by ecologists to find the main factors or gradients in large, species rich but usually sparse data matrices that typify ecological community data. For example, Hill and Gauch (1980, p. 55) … Wikipedia
