Bayesian estimation of the self-similarity exponent of the Nile River fluctuation [PDF]

open access: yesNonlinear Processes in Geophysics, 2011
The aim of this paper is to estimate the Hurst parameter of Fractional Gaussian Noise (FGN) using Bayesian inference. We propose an estimation technique that takes into account the full correlation structure of this process.

A Climate-Mathematical Clustering of Rainfall Stations in the Río Bravo-San Juan Basin (Mexico) by Using the Higuchi Fractal Dimension and the Hurst Exponent

open access: yesMathematics, 2021
When conducting an analysis of nature’s time series, such as meteorological ones, an important matter is a long-range dependence to quantify the global behavior of the series and connect it with other physical characteristics of the region of study.

An investigation on the relationship between the Hurst exponent and the predictability of a rainfall time series [PDF]

open access: bronzeMeteorological Applications, 2019
Rainfall prediction is a very challenging task due to its dependence on many meteorological parameters. Because of the complex nature of rainfall, the uncertainty associated with its predictability continues to be an issue in rainfall forecasting.

Random walks, Hurst exponent, and market efficiency

open access: yesQuality & Quantity
Market efficiency assumes that prices in financial markets are perfectly informative and, therefore, it is not possible to design trading strategies that outperform the market.

Range Entropy: A Bridge between Signal Complexity and Self-Similarity [PDF]

open access: yesEntropy, 2018
Approximate entropy (ApEn) and sample entropy (SampEn) are widely used for temporal complexity analysis of real-world phenomena. However, their relationship with the Hurst exponent as a measure of self-similarity is not widely studied. Additionally, ApEn

A fast algorithm for robust estimates of the Hurst exponent when analyzing small samples of biometric and market data

open access: diamondИзвестия высших учебных заведений. Поволжский регион:Технические науки
Background. Currently, the Hurst exponent is quite easily interpreted in relation to biometric, medical and economic data, but it is customary to evaluate it on large samples.
