Inference for unit roots in a panel smooth transition autoregressive model where the time dimension is fixed

He, Changli (contributor); Sandberg, Rickard (contributor) - 2005 - [Elektronische Ressource], Rev. February 18, 2005

In this paper we derive a unit root test against a Panel Logistic Smooth Transition Autoregressive (PLSTAR). The …, finite sample properties of the test are examined. We highlight scenarios under which the traditional panel unit root tests … by Harris and Tzavalis have inferior or reasonable power compared to our test. -- Dynamic nonlinear panel ; Smooth …

A simple efficient GMM estimator of GARCH models

Skoglund, Jimmy (contributor) - 2001 - [Elektronische Ressource]

This paper is concerned with efficient GMM estimation and inference in GARCH models. Sufficient conditions for the estimator to be consistent and asymptotically normal are established for the GARCH(1,1) conditional variance process. In addition efficiency results are obtained in the general...

Building neural network models for time series : a statistical approach

Medeiros, Marcelo C. (contributor); … - 2002 - [Elektronische Ressource]

This paper is concerned with modelling time series by single hidden-layer feedforward neural network models. A coherent modelling strategy based on statistical inference is presented. Variable selection is carried out using existing techniques. The problem of selecting the number of hidden units...

A nonlinear alternative to the unit root hypothesis

Eklund, Bruno (contributor) - 2003 - [Elektronische Ressource]

This paper considers testing the unit root hypothesis against a smooth transition autoregressive model as the alternative. The model specification makes it possible to discriminate between nonstationary random walk and stationary nonlinear processes. Some new limit results are presented,...

Univariate nonlinear time series models

Teräsvirta, Timo (contributor) - 2005 - [Elektronische Ressource]

In this paper developments in the analysis of univariate nonlinear time series are considered. First a number of commonly used nonlinear models are presented. The next section is devoted to methods of testing linearity, which is an important part of nonlinear model building. Techniques of...

Determing the number of regimes in a threshold autoregressive model using smooth transition autoregressions

Strikholm, Birgit (contributor); … - 2005 - [Elektronische Ressource], Rev. February 11, 2005

In this paper we propose a method for determining the number of regimes in threshold autoregressive models using smooth transition autoregression as a tool. As the smooth transition model is just an approximation to the threshold autoregressive one, no asymptotic properties are claimed for the...
