The Application of the Extended Poincaré Plot in the Analysis of Physiological Variabilities

open access: yesFrontiers in Physiology, 2019
The Poincaré plot is a geometrical technique used to visualize and quantify the correlation between two consecutive data points in a time-series. Since the dynamics of fluctuations in physiological rhythms exhibit long-term correlation and memory, this ...
