Generalized hurst exponent

WebIn fractal geometry, the generalized Hurst exponent has been denoted by H or H q in honor of both Harold Edwin Hurst and Ludwig Otto Hölder (1859–1937) by Benoît Mandelbrot (1924–2010). H is directly related to fractal dimension, D, and is a measure of a data series' "mild" or "wild" randomness. WebJan 1, 2024 · To estimate the generalized Hurst exponent, we use the MF-DFA, which may be applied to non-stationary time series ( Kantelhardt et al., 2002 ). The MF-DFA has become a popular method to study the multifractal properties of various time series, and studies on Bitcoin have already applied this method, including Takaishi (2024).
