Why not,
All though putting e.g. "{=POLYVAL(POLYFIT(C9:C14;D9:D14;3);C9:C14)}" in the
column next to your Y's will give you nicely fitted values (as requested earlier
in this issue). But it is still early development and needs more effort on error
handling and bug testing.
Noticed also that result from Octaves polyfit deviates slightly from Excel
Linest (while complaining that inverse matrix is singular to machine precision).
But the difference is small. I suppose one should have a number of different
methods of solving the problem, and to choose the most adequate.
