WebJun 28, 2024 · Cointegration is a phenomenon observed in a time series context. Several time series cointegrate if there exists a linear combination that is integrated of a lower order than the series themselves. (See also the tag description for cointegration .) Regression has several meanings. WebPart of R Language Collective. 1. I am currently working with different pairwise VAR models to analyze cointegration relationships. There is following pair of time series: X is I (0), Y I (1). Because X and Y are not integrated of same order (i.e. I (1) and I (1)), I can't carry out the Johansen and Juselius ( ca.jo) test with the vars package.
