Abstract

We discuss how random switching between two states in the dynamics of complex systems affects characterization of oscillations based on data analysis. The appearance of unwanted short segments with distinct correlation features can significantly change the properties of time series estimated by standard numerical methods and, therefore, complicate the diagnosis of the system dynamics. The effects of random switching are much stronger for systems with anti-correlated dynamics compared with the case of power-law correlations.
