the I(2) vector autoregressive model. It is shown that the asymptotic distribution of the LR test for the (multi … the hypothesis of I(2), and application of the LR test may change rank selection in empirical work. Based on a study of … properties when compared to the Two-Step based test. Overall, we propose to use of the LR test for rank determination in I(2 …
