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...

Testing parameter constancy in stationary vector autoregressive models against continuous change

He, Changli (contributor); Teräsvirta, Timo (contributor); … - 2002 - [Elektronische Ressource], Rev. July 11, 2005

In this paper we derive a parameter constancy test of a stationary vector autoregressive model against the hypothesis that the parameters of the model change smoothly over time. A single structural break is contained in this alternative hypothesis as a special case. The test is a generalization...
