Alpha and Beta in Johansen cointegration

Postby thefan » Thu Apr 23, 2009 8:16 am

hi can someone tell me
1) how to interpret alpha and beta coefficients (adjustment coefficient and cointegrating coefficient) of the Johansen method?
2) Where can one find these coefficient in the EViews result sheets? suppose the following is the Johansen result sheet where are the alpha and beta coefficients?
