Nonlinear Analysis

Nonlinear Analysis is a methodological framework within heart rate variability research that characterizes complex, nonstationary physiological dynamics through mathematical techniques sensitive to deterministic chaos, fractal properties, and state-dependent interactions, distinguishing it from linear analytic approaches reliant on superposition and frequency-domain decomposition.
