Surrogate Test to Distinguish between Chaotic and Pseudoperiodic Time Series
Xiaodong Luo, Tomomichi Nakamura, Michael Small
In this communication a new algorithm is proposed to produce surrogates for pseudoperiodic time series. By imposing a few constraints on the noise components of pseudoperiodic data…

Estimating the distribution of dynamic invariants: Illustrated with an application to human photo-plethysmographic time series
Michael Small
Dynamic invariants are often estimated from experimental time series with the aim of differentiating between different physical states in the underlying system. The most popular sc…
