Correlations in magnitude series to assess nonlinearities: application to multifractal models and heartbeat fluctuations

Pedro A. Bernaola-Galvan, Manuel Gomez-Extremera, A. Ramon Romance +1

The correlation properties of the magnitudes of a time series (sometimes called volatility) are associated with nonlinear and multifractal properties and have been applied in a gre…
