Re: [Gretl-users] strange R^2 with TSLS

Hello gretl users,
yet again one of those tsls-problems of mine...
It seems to me that TSLS doesn't calculate the R^2 correctly. Actually, it
produces exactly the same values as the corresponding OLS estimation. For
example, the three-liner
open denmark
ols IDE 0 IBO
tsls IDE 0 IBO; LRY
Hold on a second. Never mind the R^2 index; the tsls command should never
work here (2 regressors and 1 instrument). The fact that you manage to
get an output at all is very very wrong. I'll try to see what goes wrong
as soon as I get a chance (unlikely before tomorrow).
