(English) Zbl 1371.92012 Acta Phys. Pol. B 44, No. 5, 1219-1233 (2013). Summary: The network representations in the characterization of time series complexity is a relatively new but quickly developing branch of time series analysis. The changes in beat-to-beat time intervals, called \(RR\)-increments, can be mapped into the directed and weighted network. The vertices in this network represent \(RR\)-increments and edges correspond to pairs of subsequent increments. We show that community structure analysis, called \(p\)-core analysis, is an effective measure which allows the evaluation of the information on dynamical processes represented by networks constructed from \(RR\)-increments.
