Informational Efficiency in Cryptocurrency Markets: A Bibliometric and Thematic Literature Review (2015–2024)

Journal of Economic Surveys, Volume 40, Issue 1, Page 443-468, February 2026.
ABSTRACT Cryptocurrency markets are known for their wide price fluctuations, lack of central control, and fast‐paced development. These characteristics present serious challenges to traditional theories about how markets work and how prices reflect available information.

Multifractal detrended cross-correlation analysis for two nonstationary signals

, 2008
It is ubiquitous in natural and social sciences that two variables, recorded temporally or spatially in a complex system, are cross-correlated and possess multifractal features.

Cotton Yield Prediction Model Based on Hyperspectral Feature Fusion and Machine Learning

Modern Agriculture, Volume 3, Issue 2, December 2025.
This study integrates hyperspectral feature fusion with machine learning to advance cotton yield prediction. The approach adapts financial multifractal analysis (MF‐DFA) to agriculture by fusing fractal canopy features with vegetation indices for enhanced modelling. Results demonstrate that combining VI and fractal parameters during the flower and boll

Multifractal Analysis of Hydrologic Data Using Wavelet Methods and Fluctuation Analysis

Discrete Dynamics in Nature and Society, 2017
We study the multifractal properties of water level with a high-frequency and massive time series using wavelet methods (estimation of Hurst exponents, multiscale diagram, and wavelet leaders for multifractal analysis (WLMF)) and multifractal detrended ...
