Permutation complexity of interacting dynamical systems
Roberto Monetti, José María Amigó, Thomas Aschenbrenner +1
The coupling complexity index is an information measure introduced within the framework of ordinal symbolic dynamics. This index is used to characterize the complexity of the relat…
Information directionality in coupled time series using transcripts
Roberto Monetti, Wolfram Bunk, Thomas Aschenbrenner +2
In ordinal symbolic dynamics, transcripts describe the algebraic relationship between ordinal patterns. Using the concept of transcript, we exploit the mathematical structure of th…
Surrogates with random Fourier Phases
Christoph Raeth, Roberto A. Monetti
The method of surrogates is widely used in the field of nonlinear data analysis for testing for weak nonlinearities. The two most commonly used algorithms for generating surrogates…
Characterizing Synchronization in Time Series using Information Measures Extracted from Symbolic Representations
Roberto Monetti, Wolfram Bunk, Ferdinand Jamitzky
We present a methodology to characterize synchronization in time series based on symbolic representations. A symbol is linked to a sequence of numbers through the rank-order of its…
Detecting non-linearities in data sets. Characterization of Fourier phase maps using the Weighted Scaling Indices
Roberto A. Monetti, Wolfram Bunk, Ferdinand Jamitzky +2
We present a methodology for detecting non-linearities in data sets based on the characterization of the structural features of the Fourier phase maps. A Fourier phase map is a 2D…
Long term persistence in the sea surface temperature fluctuations
Roberto A. Monetti, Shlomo Havlin, Armin Bunde
We study the temporal correlations in the sea surface temperature (SST) fluctuations around the seasonal mean values in the Atlantic and Pacific oceans. We apply a method that syst…
