The accuracy of their functions may leave a bit to be desired, though.
I've just starting using Excel 5 and compared a simple linear regression
with the results from Systat. There was a good bit of difference in the
sums of squares. For instance Excel gave a residual SS of 1501.088 vs
Systat's 1500.565. The resulting f-ratio was 364.1975 vs 364.300. I
think I would tend to believe Systat's results more :-)
I've only tried it with this one data set so far, so I can't say how much
of a problem this is.
