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...

Testing parameter constancy in unit root autoregressive models against continuous change
He, Changli (contributor); Sandberg, Rickard (contributor) - 2005 - [Elektronische Ressource], Rev. February 8, 2005
In this paper we derive tests for parameter constancy when the data generating process is non-stationary against the hypothesis that the parameters of the model change smoothly over time. To obtain the asymptotic distributions of the tests we generalize many theoretical results, as well as new...
