[Gretl-users] Johansen

[Andreas Karlsson]

Hi,

The answer is that it does not make any difference if you are using H0: r <= r0
with H1: r > r0 or H0: r = r0 with H1: r > r0. Statistically, these two
expressions are the same. Likewise, H0: r => r0 with H1: r < r0 or H0: r = r0
with H1: r < r0 would be the same.

Regards
Andreas
