Detrended fluctuation analysis of laser Doppler flowmetry time series

Microvascular Research, 2009
Detrended fluctuation analysis (DFA) of laser Doppler flow (LDF) time series appears to yield improved prognostic power in microvascular dysfunction, through calculation of the scaling exponent, alpha. In the present study the long lasting strenuous activity-induced change in microvascular function was evaluated by DFA in basketball players compared ...

A NOVEL CORRELATION FUNCTION FROM DETRENDED FLUCTUATION ANALYSIS

Modern Physics Letters B, 2005
A method for investigating the existence of long-range correlations between two sequences is proposed from the detrended fluctuation analysis method. A new correlation function is defined and its behavior is shown for simple examples.

Detrended fluctuation analysis of heart intrabeat dynamics

Physica A: Statistical Mechanics and its Applications, 2007
Abstract We investigate scaling properties of electrocardiogram (ECG) recordings of healthy subjects and heart failure patients based on detrended fluctuation analysis (DFA). While the vast majority of scaling analysis has focused on the characterization of the long-range correlations of interbeat (i.e., beat-to-beat) dynamics, in this work we ...

Asymmetric Multifractal Detrended Fluctuation Analysis (A-MFDFA)

2018
The presence of multifractality suggests the inefficiency (Cajueiro and Tabak 2004, 2004, 2008; Cajueiro et al. 2009; Tabak and Cajueiro 2007; Wang et al. 2010), volatility predictability (Wei and Wang 2008), crash predictions (Wei and Wang 2008; Grech and Pamula 2008), and complexity (Matia et al. 2003; Kumar and Deo 2009; Norouzzadeh and Jafari 2005)
