Theoretical foundation of detrending methods for fluctuation analysis such as detrended fluctuation analysis and detrending moving average [PDF]
Physical Review E, 2019 We present a general framework of detrending methods of fluctuation analysis of which detrended fluctuation analysis (DFA) is one prominent example. Another more recently introduced method is detrending moving average (DMA). Both methods are constructed differently but are similarly able to detect long-range correlations as well as anomalous diffusion ...

DETRENDED FLUCTUATION ANALYSIS OF AUTOREGRESSIVE PROCESSES [PDF]
Fluctuation and Noise Letters, 2007 Autoregressive processes (AR) have typical short-range memory. Detrended Fluctuation Analysis (DFA) was basically designed to reveal long-range correlations in non stationary processes. However DFA can also be regarded as a suitable method to investigate both long-range and short-range correlations in non stationary and stationary systems.

Asymmetric detrended fluctuation analysis in neonatal stress [PDF]
Physiological Measurement, 2018 To detect stress in newborns by observing heart rate (HR) variability utilizing an asymmetric detrended fluctuation analysis (ADFA), we sought to determine the fractal structure of the series of inter-beat intervals, so as to distinguish the periods of acceleration of the HR from decelerations.
