MULTIFRACTAL DETRENDED FLUCTUATIONS ANALYSIS FOR IBOVESPA ASSETS

Fractals, 2021
The Efficient Market Hypothesis (EMH) can be considered the central pillar of support of the Modern Economic-Financial Theory. However, in the last few years, the EMH has been strongly contraried due to empirical evidence related to long-memory, fractal dimension and fat-tailed that were critical factors in formulating a theory opposed to EMH called ...

Detrended Fluctuation Analysis of Traffic Data

Chinese Physics Letters, 2007
Different routing strategies may result in different behaviour of traffic on internet. We analyse the correlation of traffic data for three typical routing strategies by the detrended fluctuation analysis (DFA) and find that the degree of correlation of the data can be divided into three regions, i.e. weak, medium, and strong correlation.

Evenly spacing in Detrended Fluctuation Analysis

Physica A: Statistical Mechanics and its Applications, 2016
Abstract Detrended Fluctuation Analysis is a widely used method, which aims at assessing the level of self-similarity in time series. This method analyzes the diffusion properties of the signal, by computing the linear regression slope in the diffusion plot, representing in log–log coordinates the relationship between the variability of the signal ...

Extended detrended fluctuation analysis of electroencephalograms signals during sleep and the opening of the blood-brain barrier.

Chaos, 2020
Detrended fluctuation analysis (DFA) is widely used to characterize long-range power-law correlations in complex signals. However, it has restrictions when nonstationarity is not limited only to slow variations in the mean value.

Epilepsy detection using Detrended Fluctuation Analysis

2009 International Conference on Wavelet Analysis and Pattern Recognition, 2009
Epilepsy is a disorder of the central nervous system characterized by the loss of consciousness and convulsions. If some early warning signal of an upcoming seizure (diagnosis of preictal period) could be detected, proper treatment could be applied to the patient to help prevent the seizure.

Detrended fluctuation analysis of repetitive handwriting

2017 International Conference on Noise and Fluctuations (ICNF), 2017
Although there is a tendency that the opportunity to write by hand is decreasing, handwriting is still one of the everyday activities of our lives. In this study, the experimental system that limits the writing speed of a subject was set up. The aim was to measure the fluctuation time series of a time element obtained from the measurement performed ...
