Topic: R squared value

Why does it say my r squared value is -41?  Is that even possible :S  I'm not sure where I've gone wrong...

Re: R squared value

No eveyrthing is fine here. Check the doc file. It is the same as your graph file.

Re: R squared value

But how can an r squared value be -41?  I thought it had to be between -1 and 1.

Re: R squared value

If I remember correctly R^2 is only between 0 an 1 for linear regressions.  You can find more information in Wikipedia: http://en.wikipedia.org/wiki/R_squared
