This suggests a new methodology for exploratory data analysis and for testing the hypothesis of long-memory and of the existence of a co integrating relationship. We illustrate the performances of the new techniques with some simulation experiments, and finally apply them to the analysis of the relationship between pairs of financial time series from a foreign exchangerate and a stock return markets.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 EspañaInformation-theoretic statisticslong memorycointegrationnonlinearitycausalityworking paperEstadísticaopen access
