Weird Johansen Test Result

Postby vtov » Sat Apr 21, 2012 9:54 pm

Hi all,

I need help in figuring out the weird result I have gotten from Johansen Test.
It seems that after running the test for 5 variables, the trace test indicated 5 Coint. Eq. which doesn't make sense.
Is this a telltale sign that something is wrong eg model misspecification, lag selection etc... or just that this kind of thing happen now and then?

Thanks

Its okay, I got it. For future reference for others facing the same problem, when this happens, it means that none of the variables have stochastic trend, in which case either you recheck stationarity of your variables or if your variables are confirmed I(1) i.e in theory in cases such as stock prices, then use max eigenvalue test instead if it points to a different but valid result.
