Further side note regarding Excel -
I use their Data Analysis add-in occasionally to do a quick regression, t
test etc. - handy if you're at home!
BUT Excel isn't always accurate (Knusel 1998 and McCullough & Wilson 1999,
both in Computational Statistics and Data Analysis)
So I do still use it, and personally I haven't found any discrepancies, but
I'd always double-check my results in another package before publishing
anything based on it.
