Space time-index plots for probing dynamical nonstationarity
نویسندگان
چکیده
We propose a simple method to efficiently probe dynamical nonstationarity in observed time series. In a space time-index plot, the density distributions as a function of normalized time-index are V-shaped due to nonstationarity. We show that this method is workable for short data sets and typical examples are illustrated. c © 1998 Elsevier Science B.V. PACS: 02.50.+s; 05.45.+b

Measuring nonstationarity by analyzing the loss of recurrence in dynamical systems.
We propose a measure for nonstationarity which is based on the analysis of distributions of temporal distances of neighboring vectors in state space. As an extension of previous techniques our method does not require a partitioning of the time series. Moreover, the deviation of mean recurrence times from frequency distributions that would be expected under stationary conditions allows us to est...
متن کاملStationary versus Nonstationary Modeling for Nonlinear Time Series
Many natural time series may have nonlinearity and nonstationarity. Although interpreting complex phenomena by the theory of nonlinear dynamical systems have been successful, it is still important to consider how to deal with nonstationarity in time series. In this paper, we analyze nonstationary time series by stationary versus nonstationary modeling in order to discuss the present issue.

متن کاملEEG nonstationarity during intracranially recorded seizures: statistical and dynamical analysis.
OBJECTIVE The investigation of nonstationarity in complex, multivariable signals, such as electroencephalographic (EEG) recordings, requires the application of different and novel approaches to analysis. In this study, we have divided the EEG recordings during epileptic seizures into sequential stages using spectral and statistical analysis, and have as well reconstructed discrete-time models (...
متن کاملDynamical density delay maps: simple, new method for visualising the behaviour of complex systems
BACKGROUND Physiologic signals, such as cardiac interbeat intervals, exhibit complex fluctuations. However, capturing important dynamical properties, including nonstationarities may not be feasible from conventional time series graphical representations. METHODS We introduce a simple-to-implement visualisation method, termed dynamical density delay mapping ("D3-Map" technique) that provides a...
