Hurst exponent wikipedia
Web28 jun. 2024 · Description. The Hurst exponent is referred to as the “index of dependence” or “index of long-range dependence”. It quantifies the relative tendency of a time series either to regress strongly to the mean or to cluster in a direction. A value H in the range 0.5–1 indicates a time series with long-term positive autocorrelation, meaning ... Web12 jan. 2024 · I haven't looked at the source code yet, but the estimate "Corrected R over S Hurst exponent" came back as 1.09. This is not too far from my value of 1.03, which was also done with an R/S analysis. Because of this, I've made an executive decision to not worry about this any longer. Jan 12, 2024. #5.

[3] H is directly related to fractal dimension, D, and is a measure of a data series' "mild" or "wild" randomness. [4] The Hurst exponent is referred to as the "index …
WebThe Hurst exponent is used as a measure of long-term memory of time series. It relates to the autocorrelations of the time series, and the rate at which these decrease as the lag … Consider a bounded time series of length , where , and let its mean value be denoted . Integration or summation converts this into an unbounded process : is called cumulative sum or profile. This process converts, for example, an i.i.d. white noise process into a random walk. Next, is divided into time windows of length samples each, and a local least squares straight-line fi…
