Hoelder-exponent-MFDFA-based test for long-range correlations in pseudorandom sequences
Nikolay K. Vitanov, Kh. Tarnev, H. Kantz
We discuss the problem for detecting long-range correlations in sequences of values obtained by generators of pseudo-random numbers. The basic idea is that the H{ö}lder exponent fo…
Multifractal analysis of the long-range correlations in the cardiac dynamics of Drosophila melanogaster
Nikolay K. Vitanov, Elka D. Yankulova
Time series of heartbeat activity of humans can exhibit long-range correlations. In this paper we show that such kind of correlations can exist for the heartbeat activity of much s…
On correlations and fractal characteristics of time series
Nikolay K. Vitanov, kenschi Sakai, Elka D. Yankulova
Correlation analysis is convenient and frequently used tool for investigation of time series from complex systems. Recently new methods such as the multifractal detrended fluctuati…
