Entropy in the natural time domain
2004
Physical Review E
A surrogate data analysis is presented, which is based on the fluctuations of the "entropy" S defined in the natural time-domain [Phys. Rev. E 68, 031106, 2003]. This entropy is not a static one as, for example, the Shannon entropy. The analysis is applied to three types of time-series, i.e., seismic electric signals, "artificial" noises and electrocardiograms, and "recognizes" the non-Markovianity in all these signals. Furthermore, it differentiates the electrocardiograms of healthy humans
