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.

Power considerations for the application of detrended fluctuation analysis in gait variability studies. [PDF]

PLoS ONE, 2017
The assessment of gait variability using stochastic signal processing techniques such as detrended fluctuation analysis (DFA) has been shown to be a sensitive tool for evaluation of gait alterations due to aging and neuromuscular disease.

Extended Detrended Fluctuation Analysis of Coarse-Grained Time Series [PDF]

Diagnostics, 2022
A coarse-graining procedure, which involves averaging time series in non-overlapping windows followed by processing of the obtained multiple data sets, is the initial step in the multiscale entropy computation method.

On the Validity of Detrended Fluctuation Analysis at Short Scales [PDF]

Entropy, 2021
Detrended Fluctuation Analysis (DFA) has become a standard method to quantify the correlations and scaling properties of real-world complex time series. For a given scale ℓ of observation, DFA provides the function F(ℓ), which quantifies the fluctuations

Detrended fluctuation analysis of earthquake data [PDF]

Physical Review Research, 2021
The detrended fluctuation analysis (DFA) is extensively useful in stochastic processes to unveil the long-term correlation. Here, we apply the DFA to point processes that mimic earthquake data.

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 ...

Detrended fluctuation analysis of intertrade durations [PDF]

Physica A: Statistical Mechanics and its Applications, 2008
The intraday pattern, long memory, and multifractal nature of the intertrade durations, which are defined as the waiting times between two consecutive transactions, are investigated based upon the limit order book data and order flows of 23 liquid ...
