Abstract

Tail approximation of the asymptotic distribution of the log likelihood ratio test for cointegration in a vector autoregressive process is studied. An approximation of weighted chi-square type is derived applying multivariate saddlepoint approximation techniques to a Fourier inversion integral

 Key words: Cointegration, Likelihood ratio test, Multivariate saddlepoint approximation.
