[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 produces the following output (excerpt): ols: Unkorrigiertes R-Quadrat = 0.644317 Korrigiertes R-Quadrat = 0.637606 tsls: Unkorrigiertes R-Quadrat = 0.644317 Korrigiertes R-Quadrat = 0.637606 I'm going to file a bug report soon if nobody stops me by saying that it all makes perfect sense... thanks, sven
