Title: | Surrogate test for pseudoperiodic time series data | Authors: | Small, M Yu, D Harrison, RG |
Issue Date: | 29-Oct-2001 | Source: | Physical review letters, 29 Oct. 2001, v. 87, no. 18, 188101, p. 1-4 | Abstract: | For time series exhibiting strong periodicities, standard (linear) surrogate methods are not useful. We describe a new algorithm that can test against the null hypothesis of a periodic orbit with uncorrelated noise. We demonstrate the application of this method to artificial data and experimental time series, including human electrocardiogram recordings during sinus rhythm and ventricular tachycardia. | Keywords: | Algorithms Approximation theory Computer simulation Electrocardiography Mathematical models Random processes Vectors White acoustic noise |
