Polynomial regression

[EpsilonRho]

Is there any way to transfer automatically the polynomial regression factors
(of a higher order) calculated in charting to a spreadsheet without being
forced to copying them by hand, digit by digit?
TIA,
Gene

Unless you are fitting a higher order polynomial, where you need the better
algorithm of the chart trendline to get meaningful results, it is easier to
use LINEST for this purpose

Tushar Mehta has enhanced VBA code by David Braden to extract
coefficients from the chart trendline.
