If you increase the Order of the Polynomial, the fitting will become tighter.So, I would be skeptical about using that equation function, at least outside of the range of values for the raw data. When I add more points to the range, for example increasing it to -11 to +16, the equation Excel generates is now y = x^2 - 29x + 210. When I use the equation function in Excel for a polynomial, it gives y = x^2 - 15x + 56. I plotted the quadratic y = x^2 - 5x + 6 between -4 and +9.Moving Average doesn't give an equation I can't remember now if I had tried polynomial but a couple things after experimenting: They are identifiable with a special user flair.Ī community since MaAsking a question?
