We welcome the submission of theoretical and practice-related application relating to fractional ... WebJun 1, 2024 · In addition, classical methods to estimate the Hurst exponent lead to different estimates for this criterion. To fill this gap, in this study, we propose an entropy-based estimator of the Hurst exponent relying on distributive features of the series in fractional Brownian motion (fBm), which is the key model of long-term memory processes.
