I wonder if the coefficient of determination, which usually ranges from -1 to +1, can achieve other values for nonlinear relations. I read something like that in an artikel which said that this is shown in GREENE, W. H., Econometric analysis (1997), p. 318.
Unfortunately I can't get the book the next weeks, so I'd be glad about any comments on the topic or some hints to other literature sources. Thanks a lot, Bastian . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
