Method of judging efficacy of biological state action affecting bioligical state, judging apparatus, judging system, judging program and recording medium holding the program

摘要

A method of judging a biological state comprising using: (1) correlation and/or symmetry between Lyapunov exponent and entropy; and/or (2) Higuchi fractal dimension, wherein the Lyapunov exponent, entropy and Higuchi fractal dimension are indices that can express chaotic nature and derived from time series data of biological signals from a subject.
