TY - JOUR A1 - Ebeling, Werner A1 - Molgedey, Lutz A1 - Kurths, Jürgen A1 - Schwarz, Udo T1 - Entropy, complexity, predictability, and data analysis of time series and letter sequences N2 - The structure of time series and letter sequences is investigated using the concepts of entropy and complexity. First conditional entropy and transinformation are introduced and several generalizations are discussed. Further several measures of complexity are introduced and discussed. The capability of these concepts to describe the structure of time series and letter sequences generated by nonlinear maps, data series from meteorology, astrophysics, cardiology, cognitive psychology and finance is investigated. The relation between the complexity and the predictability of informational strings is discussed. The relation between local order and the predictability of time series is investigated.
