Abstract in another language
When calculating the Bandt and Pompe ordinal pattern distributionfrom given time series at depth D, some of the D! patterns might not appear. This could be a pure nite size eect (missing patterns) or due to dynamical properties of the observed system (forbidden patterns). For pure noise, no forbidden patterns occur, contrary to deterministic chaotic maps. We investigate long time series of river runoff for missing patterns and calculate two global properties of their patterndistributions: the Permutation Entropy and the Permutation Statistical Complexity. This is compared to purely stochastic but long-range correlated processes, the k-noise (noise with power spectrum f-k), where k is a parameter determining the strength of the correlations. Although these processes closely resemble runo series in their correlation behavior, the ordinal pattern statistics reveals qualitative dierences, which can be phrased in terms of missing patterns behavior or the temporal asymmetry of the observed series. For the latter, an index is developed in the paper, which may be used to quantify the asymmetry of natural processes as opposed to articially generated data.
