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.

Consistency of detrended fluctuation analysis [PDF]
Physical Review E, 2017 The scaling function $F(s)$ in detrended fluctuation analysis (DFA) scales as $F(s)\sim s^{H}$ for stochastic processes with Hurst exponents $H$. We prove this scaling law for both stationary stochastic processes with $01$. As a final application of the new theory, we present an estimator $\hat F(s)$ that can handle missing data in regularly sampled ...
