Detrending flucuation analysis
WebDetrended fluctuation analysis (DFA) was first proposed by Peng et al. for detecting the long-range correlations of DNA sequences in 1995 . Afterwards, an extension of DFA called multifractal detrending fluctuation analysis (MFDFA) was proposed by Kantelhardt et al. for examining the multifractality of non-stationary time series in 2002 [ 29 ].

WebA novel multifractal detrended fluctuation analysis based on improved empirical mode decomposition for the non-linear and non-stationary vibration signal of machinery is proposed. As the intrinsic mode functions selection and Kolmogorov-Smirnov test are utilized in the detrending procedure, the present approach is quite available for ... WebThe aim of this study is to evaluate how far the detrended fluctuation analysis (DFA) approach helps to characterize the short-term and intermediate-term fractal correlations in the raw electrocardiogram (ECG) signals and thereby discriminate between normal and congestive heart failure (CHF) subjects.

Web2.3. Detrended fluctuation analysis The Detrended Fluctuation Analysis (DFA) permits the detection of long-range correlations embedded in a seemingly non-stationary time series, and also avoids the spurious detection of some apparent long-range correlations that are an artefact induced by non-stationarity [10]. WebWe show Detrended Fluctuation Analysis introduces artifacts for nonlinear trends, in contrast to common expectation, and demonstrate that the empirically observed …
