Hi
I have plotted a trend line based on some actual known data. I have
then manually calculated the y figure by plugging in the trend line
formula.
y = 5E-05x4 - 0.0283x3 + 5.4408x2 - 521.05x + 29719
On that attachment you can see a difference in results even though its
the same trend line.
Any ideas?
Thanks
