In this work we perform a fractal analysis of 160 pieces of music belonging to six different genres. We show that the majority of the pieces reveal characteristics that allow us to…
Quantitative features of multifractal subtleties in time series
Stanislaw Drozdz, Jaroslaw Kwapien, Pawel Oswiecimka +1
Based on the Multifractal Detrended Fluctuation Analysis (MFDFA) and on the Wavelet Transform Modulus Maxima (WTMM) methods we investigate the origin of multifractality in the time…
Correlation matrix decomposition of WIG20 intraday fluctuations
R. Rak, S. Drozdz, J. Kwapien +1
Using the correlation matrix formalism we study the temporal aspects of the Warsaw Stock Market evolution as represented by the WIG20 index. The high frequency (1 min) WIG20 record…
Nonextensive statistical features of the Polish stock market fluctuations
R. Rak, S. Drozdz, J. Kwapien
The statistics of return distributions on various time scales constitutes one of the most informative characteristics of the financial dynamics. Here we present a systematic study…
