The nature of such dependencies is typically not only nonlinear but also asymmetric and thus makes the use of symmetric and linear methods ineffective. Moreover, signals sampled from real world systems are noisy and short, posing additional constraints on the estimation of the underlying couplings. In this article, we compare a set of six recently introduced methods for quantifying the causal structure of bivariate time series extracted from systems with complex dynamical behavior. We discuss the usefulness of the methods for detecting asymmetric couplings and directional flow of information in the context of uni- and bidirectionally coupled deterministic chaotic systems. <\/jats:p>","DOI":"10.1142\/s0218127407017628","type":"journal-article","created":{"date-parts":[[2007,5,15]],"date-time":"2007-05-15T20:45:51Z","timestamp":1179261951000},"page":"903-921","source":"Crossref","is-referenced-by-count":95,"title":["METHODS FOR QUANTIFYING THE CAUSAL STRUCTURE OF BIVARIATE TIME SERIES"],"prefix":"10.1142","volume":"17","author":[{"given":"M.","family":"LUNGARELLA","sequence":"first","affiliation":[{"name":"Intelligent Systems and Informatics Laboratory, Department of Mechano-Informatics, University of Tokyo, 113-8656 Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"ISHIGURO","sequence":"additional","affiliation":[{"name":"Intelligent Systems and Informatics Laboratory, Department of Mechano-Informatics, University of Tokyo, 113-8656 Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"KUNIYOSHI","sequence":"additional","affiliation":[{"name":"Intelligent Systems and Informatics Laboratory, Department of Mechano-Informatics, University of Tokyo, 113-8656 Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"OTSU","sequence":"additional","affiliation":[{"name":"Intelligent Systems and Informatics Laboratory, Department of Mechano-Informatics, University of Tokyo, 113-8656 Tokyo, Japan"},{"name":"National Institute of Advanced Industrial Science and Technology, 305-8568 Tsukuba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,20]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.70.056221"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-2789(99)00140-2"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1109\/TSMCB.2003.808175"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1016\/j.physleta.2004.02.032"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.59.845"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127404009314"},{"key":"rf7","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.33.1134"},{"key":"rf8","doi-asserted-by":"publisher","DOI":"10.1016\/j.physa.2004.11.043"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.2307\/1912791"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1007\/BF01608556"},{"key":"rf11","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevA.45.3403"},{"key":"rf12","doi-asserted-by":"publisher","DOI":"10.1140\/epjb\/e2002-00379-2"},{"key":"rf13","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.45.712"},{"key":"rf14","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevE.67.055201"},{"key":"rf15","unstructured":"U.\u00a0Parlitz and L.\u00a0Kocarev, Handbook of Chaos Control, ed.
