Quantifying Memory in Complex Physiological Time-Series
Figure 4
The probability distribution of the normalized exit times (τ) needed to observe a decelerating event that is ρ = σ second slower than a given point (t) within the time-series (ΔB = Bt+τ−Bt ≥σ).
Cardiac inter-beat interval time-series were obtained from (a) 41 healthy volunteers and (b) 93 patients with liver cirrhosis. Blue solid lines represent probability distribution of τ of original time-series and red dash-dot lines correspond to their shuffled time-series. Data are presented as mean ± standard error of mean.
