A Matlab program and user's guide for the fractionally cointegrated VAR model

Nielsen, Morten Ørregaard; Popiel, Michal Ksawery - 2014

This manual describes the usage of the accompanying freely available Matlab program for estimation and testing in the fractionally cointegrated vector autoregressive (FCVAR) model. This program replaces an earlier Matlab program by Nielsen and Morin (2014), and although the present Matlab...

Testing the CVAR in the fractional CVAR model

Johansen, Søren; Nielsen, Morten Ørregaard - 2017

We consider the fractional cointegrated vector autoregressive (CVAR) model of Johansen and Nielsen (2012a) and show that the test statistic for the ususal CVAR model is asymptotically chi-squared distributed. Because the usual CVAR model lies on the boundary of the parameter space for the...

The cointegrated vector autoregressive model with general deterministic terms

Johansen, Søren; Nielsen, Morten Ørregaard - 2016

In the cointegrated vector autoregression (CVAR) literature, deterministic terms have until now been analyzed on a case-by-case, or as-needed basis. We give a comprehensive uni ed treatment of deterministic terms in the additive model Xt = γZt + Yt, where Zt belongs to a large class of...

Inference on the dimension of the nonstationary subspace in functional time series

Nielsen, Morten Ørregaard; Seo, Won-Ki; Seong, Dakyung - 2019

We propose a statistical procedure to determine the dimension of the nonstationary subspace of cointegrated functional time series taking values in the Hilbert space of square-integrable functions defined on a compact interval. The procedure is based on sequential application of a proposed test...

Truncated sum of squares estimation of fractional time series models with deterministic trends

Hualde, Javier; Nielsen, Morten Ørregaard - 2017

We consider truncated (or conditional) sum of squares estimation of a parametric model composed of a fractional time series and an additive generalized polynomial trend. Both the memory parameter, which characterizes the behaviour of the stochastic component of the model, and the exponent...

Nearly efficient likelihood ratio tests of a unit root in an autoregressive model of arbitrary order

Brien, Samuel; Jansson, Michael; Nielsen, Morten Ørregaard - 2020

We study large-sample properties of likelihood ratio tests of the unit root hypothesis in an autoregressive model of arbitrary, finite order. Earlier research on this testing problem has developed likelihood ratio tests in the autoregressive model of order one, but resorted to a plug-in approach...
