How do I access the curve fit coefficients? For example, I want to curve fit a 2nd order polynomial to a set of data and display the coefficients in separate cells then evaluate the curve fit at a defined X value (say cell B5); i.e. y = A5*B5^2 + A6*B5 + A7. So how do I extract the coefficients without copy and paste and get them in column A?
Next time around I drag and drop in new data and my new Y value is immediately calculated. And I want to do this without a macro. Hopefully I was able to sufficiently describe this.
