Re: Gnumeric regression is wrong?

For multiple regression there is defintiely much more wrong. Attached is a gnumeric file in which the data analysis regression tool was used to perform a regression of the dependent systolic blood pressure with respect to the independent variables age and weight. Clearly the r squared should not be -1.1 times 10 to the 12th... I would have liked to see 0.8629.

This is current CVS.

There is definitely something wrong with the regression calculations in the data analysis tools. It seems that the standrard error for the parameter estimates are switched (and then all the calculations based on them seem to be wrong).

I'll try to locate the exact problem.
