An Excess Entropy Approach to Classify Long-Term and Short-Term Memory Stationary Time Series

Autor: Xuyan Xiang, Jieming Zhou

Publikováno v: Mathematics, Vol 11, Iss 11, p 2448 (2023)

Long-term memory behavior is one of the most important phenomena that has appeared in the time series analysis. Different from most definitions of second-order properties, an excess entropy approach is developed for stationary time series to classify

A Study of Fractality and Long-Range Order in the Distribution of Transposable Elements in Eukaryotic Genomes Using the Scaling Properties of Block Entropy and Box-Counting

Autor: Labrini Athanasopoulou, Diamantis Sellis, Yannis Almirantis

Publikováno v: Entropy, Vol 16, Iss 4, Pp 1860-1882 (2014)

Repeats or Transposable Elements (TEs) are highly repeated sequence stretches, present in virtually all eukaryotic genomes. We explore the distribution of representative TEs from all major classes in entire chromosomes across various organisms. We em

The values of Block Entropy for patients with Congestive Heart Failure

Autor: Tessmer, Katarzyna, Graff, Grzegorz

The dataset consists of calculated values of entropy of 75 000 intervals between consecutive heartbeats (RR intervals) for 29 patients with congestive heart failure (CHF). The original data were taken from PhysioNet Congestive Heart Failure RR Interv

The Flow of Information in Trading: An Entropy Approach to Market Regimes

Autor: Liu, Anqi, Chen, Jing, Yang, Steve Y., Hawkes, Alan G., Alan Hawkes, Steve Yang

Publikováno v: Entropy
Entropy, Vol 22, Iss 1064, p 1064 (2020)
Volume 22
Issue 9

In this study, we use entropy-based measures to identify different types of trading behaviors. We detect the return-driven trading using the conditional block entropy that dynamically reflects the &ldquo
self-causality&rdquo
of market retur

Autor: Iulia Lupu, Adina Criste, Radu Lupu

Publikováno v: Entropy
Volume 23
Issue 9
Entropy, Vol 23, Iss 1213, p 1213 (2021)

The pattern of financial cycles in the European Union has direct impacts on financial stability and economic sustainability in view of adoption of the euro. The purpose of the article is to identify the degree of coherence of credit cycles in the cou

Foreign exchange rate entropy evolution during financial crises

Autor: Dusan Stosic, Darko Stosic, Teresa B. Ludermir, Tatijana Stosic, Wilson Rosa de Oliveira

Publikováno v: Physica A: Statistical Mechanics and its Applications. 449:233-239

This paper examines the effects of financial crises on foreign exchange (FX) markets, where entropy evolution is measured for different exchange rates, using the time-dependent block entropy method. Empirical results suggest that financial crises are

Entanglement entropy and the Berezinskii–Kosterlitz–Thouless phase transition in the J 1 – J 2 Heisenberg chain

Autor: Yan-Chao Li, Zi-Gang Yuan, Yuan-Hui Zhu

Publikováno v: Physics Letters A. 380:1066-1070

Using the density matrix renormalization group (DMRG) technique, we study the Berezinskii–Kosterlitz–Thouless (BKT) quantum phase transition (QPT) in the J 1 – J 2 Heisenberg chain model from the quantum entanglement point of view. It is found
