I investigate the relationship among 3 variables (XMIN, LPIB, LIPI). I found that all variables are stationnary in their first differences. Johansen's cointegration method has been adopted to examine the long run relationship among the variables. I found that there is one cointegrating vector in the model.
Now, it is convenient to make the test based on vector error correction models (VECM), so I made the test with Eviews and I don't know how to interpret the table.
