Geometric Ergodicity of Nonlinear Time Series
نویسنده
چکیده
We identify conditions for geometric ergodicity of general, and possibly nonparametric, nonlinear autoregressive time series. We also indicate how a condition for ergodicity, with minimal side assumptions, may in fact imply geometric ergodicity. Our examples include models for which exponential stability of the associated (noiseless) dynamical system is not sufficient or not necessary, or both.

Geometric Transience of Nonlinear Time Series
In this paper we provide conditions for nonlinear time series to be geometrically explosive with positive probability. The paper complements earlier work by the authors on geometrically ergodic nonlinear time series, showing that the conditions for examples in the earlier paper are sharp. We also study the transience of polynomial autoregression models.
متن کاملThe ACRModel: AMultivariate Dynamic Mixture AutoregressionÅ
This paper proposes and analyses the autoregressive conditional root (ACR) time-series model. This multivariate dynamic mixture autoregression allows for non-stationary epochs. It proves to be an appealing alternative to existing nonlinear models, e.g. the threshold autoregressive or Markov switching class of models, which are commonly used to describe nonlinear dynamics as implied by arbitrage...
متن کاملOn $L_1$-weak ergodicity of nonhomogeneous continuous-time Markov processes
In the present paper we investigate the $L_1$-weak ergodicity of nonhomogeneous continuous-time Markov processes with general state spaces. We provide a necessary and sufficient condition for such processes to satisfy the $L_1$-weak ergodicity. Moreover, we apply the obtained results to establish $L_1$-weak ergodicity of quadratic stochastic processes.
متن کاملNonlinear stability and ergodicity of ensemble based Kalman filters
The ensemble Kalman filter (EnKF) and ensemble square root filter (ESRF) are data assimilation methods used to combine high dimensional, nonlinear dynamical models with observed data. Despite their widespread usage in climate science and oil reservoir simulation, very little is known about the long-time behavior of these methods and why they are effective when applied with modest ensemble sizes...
متن کاملMeasuring Statistical Dependences in a Time SeriesBernd
We propose two methods to measure all (linear and nonlinear) statistical dependences in a stationary time series. Presuming ergodicity, the measures can be obtained from eecient numerical algorithms.
