Wavelet versus Detrended Fluctuation Analysis of multifractal structures [PDF]

Physical Review E, 2006
We perform a comparative study of applicability of the Multifractal Detrended Fluctuation Analysis (MFDFA) and the Wavelet Transform Modulus Maxima (WTMM) method in proper detecting of mono- and multifractal character of data. We quantify the performance

Multifractal Detrended Fluctuation Analysis of Human gait Diseases [PDF]

Frontiers in Physiology, 2013
IIn this paper multifractal detrended fluctuation analysis is used to study the human gait time series for normal and diseased sets. It is observed that long range correlation is primarily responsible for the origin of multifractality.

Effect of Trends on Detrended Fluctuation Analysis [PDF]

Physical Review E, 2001
Detrended fluctuation analysis (DFA) is a scaling analysis method used to estimate long-range power-law correlation exponents in noisy signals. Many noisy signals in real systems display trends, so that the scaling results obtained from the DFA method ...

Effect of nonstationarities on detrended fluctuation analysis [PDF]

Physical Review E, 2001
Detrended fluctuation analysis (DFA) is a scaling analysis method used to quantify long-range power-law correlations in signals. Many physical and biological signals are ``noisy'', heterogeneous and exhibit different types of nonstationarities, which can

Multifractal detrended fluctuation analysis of human EEG: preliminary investigation and comparison with the wavelet transform modulus maxima technique. [PDF]

PLoS ONE, 2013
Recently, many lines of investigation in neuroscience and statistical physics have converged to raise the hypothesis that the underlying pattern of neuronal activation which results in electroencephalography (EEG) signals is nonlinear, with self-affine ...

Objective differentiation of neonatal EEG background grades using detrended fluctuation analysis [PDF]

Frontiers in Human Neuroscience, 2015
A quantitative and objective assessment of background electroencephalograph (EEG) in sick neonates remains an everyday clinical challenge. We studied whether long range temporal correlations quantified by detrended fluctuation analysis (DFA) could be ...
