The two solid lines (left Y axis) depict the evolution of the time series length required to reach a 90% detection of irreversibility for the logistic map, according to the ... WebThe time simmetry statistic measures the asymmetry of a time series under time reversal by calculating: E [s_n\cdot s_ {n+1}^2] - E [s_n^2\cdot s_ {n+1}] E [sn ⋅sn+12]−E [sn2 ⋅sn+1] . Since linear stochastic series are symmetric under time reversal, this statistic may be used for testing the assertion that the data was generated from a ...

Time series irreversibility: a visibility graph approach

WebWe propose a method to measure real-valued time series irreversibility which combines two different tools: the horizontal visibility algorithm and the Kullback-Leibler divergence. This method maps a time series to a directed network according to a geometric criterion. The degree of irreversibility of the series is then estimated by the Kullback-Leibler divergence … WebAug 8, 2011 · We propose a method to measure real-valued time series irreversibility which combines two differ- ent tools: the horizontal visibility algorithm and the Kullback-Leibler … easy flex pain relief capsules https://sptcpa.com
