Re: Gnumeric regression is wrong?

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.

Gnumeric's regression stuff is supposed to match Excel's, modulo
bugs (in either).

Please supply a concrete example of a regression that Gnumeric
does differently than Excel:

* The data.
* The result you get from Gnumeric.
* The result you get from Excel.
* The versions of Gnumeric and Excel you are using.

We're probably not too interested in bugs before, say, Gnumeric
version 0.64.  Please check a newer version first.
