Panel Unit Root & Panel Cointegration
Posted: Thu Jan 19, 2017 6:45 pm
Dear friends,
I strongly need your helps on this matter.
I have total 372 data with 54 years and 7 countries, total 5 variables namely Y, L, F, I, S where S is dummy variable and Y is independent variables.
I have tested unit root test for these 5 variables, and found except S is stationary at level others is stationary at first difference.
Thus, I proceed to panel cointegration test (Pedroni, Kao and Fisher/Johansen test). Below are conclusion can be drawn from results display from Eviews (as attached):
Pedroni Test: No cointegration among variables
Kao Test: cointegration among variables
Fisher Test: At most 1 cointegration among variables (significance of none cointegration is very high compare to at most 1 cointegration among variables)
Can I conclude that these variables are not cointegrated? As I am going to proceed to PMG test, thus cointegration results seems important to identify long run relationship did exist before we can proceed further.
Besides, I do not find ARDL Bound test for panel which is more suitable to test I(0) and I(1) data.
Thanks for your helps & advises in advance.
