Jumps Activity and Singularity Spectra for Instruments in the Polish Financial Market

Kliber, Pawel - In: Dynamic Econometric Models 11 (2011), pp. 171-184

In the paper we try to measure the activity of jumps in returns of some instruments from the Polish financial market. We use Blumenthal-Getoor index ? for Lévy processes as a measure of jumps’ activity. This allows us to distinguish between processes with rare and sharp jumps and the...

Multifractal detrended fluctuation analysis of particle density fluctuations in high-energy nuclear collisions

Mali, P.; Sarkar, S.; Ghosh, S.; Mukhopadhyay, A.; Singh, G. - In: Physica A: Statistical Mechanics and its Applications 424 (2015) C, pp. 25-33

The detrended fluctuation analysis (DFA) and the multifractal DFA (MF-DFA) techniques are employed to characterize the pseudorapidity (η) distribution of charged mesons produced in 28Si+Ag/Br interaction at 14.5 GeV/nucleon and 32S+Ag/Br interaction at 200 GeV/nucleon. Various multifractal...

The Hausdorff spectrum of a class of multifractal processes

Decrouez, Geoffrey; Hambly, Ben; Jones, Owen Dafydd - In: Stochastic Processes and their Applications 125 (2015) 4, pp. 1541-1568

The Multifractal Embedded Branching Process (MEBP) process and Canonical Embedded Branching Process (CEBP) process were introduced by Decrouez and Jones (2012). The CEBP is a process in which the crossings of dyadic intervals constitute a branching process. An MEBP process is defined as a...

Multifractals of central place systems: Models, dimension spectrums, and empirical analysis

Chen, Yanguang - In: Physica A: Statistical Mechanics and its Applications 402 (2014) C, pp. 266-282

Central place systems have been demonstrated to possess self-similarity in both the theoretical and empirical perspectives. A central place model can be treated as a monofractal with a single scaling process. However, a real system of human settlements is a complex network with multi-scaling...

A multifractal detrended fluctuation analysis (MDFA) of the Chinese growth enterprise market (GEM)

Wang, Hui; Xiang, Luojie; Pandey, R.B. - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 12, pp. 3496-3502

A multifractal, detrended fluctuation approach is used to analyze the growth enterprise market (GEM) in China involving a range of correlations in fluctuations of share prices (fat tail), persistent and anti-persistent states. Our analysis exhibits company-specific multifractal characteristics,...
