A series generated by the first difference is integrated of order 1 denoted as I (1). Thus, if a time series, is I (0), it is stationary; if it is I (1) then its change is stationary and its level is non-stationary. The equation for the cointegration test is given below: P=m-k. Case I: When k=0, then p=m, it means variables in time series are.

From the test results above, we will reject null hypothesis of \(r=0\) easily. We can reject \(r\leq1\) up to 90% confidence level. There's another 10% of chance that \(r\) is 1 or based on (A6), they are cointegrated. It seems that Johansen test is more strict than the CDAF test regarding to accepting pairs.

Johansen Test. Johansen test uses the VECM to find the cointegration coefficient/vector . The most important improvement of Johansen Test compared to Engle-Granger test is that it treats every asset as an independent variable. Johansen test also provides two test statistics, eigenvalue statistics and trace statistics, to determine if the asset.
