Click here to learn more about Real Statistics capabilities that support polynomial regression. Excel Capabilities. We look at a quadratic model, although it is straightforward to extend this to any higher-order polynomial. The polynomial regression is a multiple linear regression from a technical point of view. However, we do not interpret it the same way. It is often quite challenging to look at individual coefficients, as the underlying predictors (independent variables) in a polynomial regression model may experience a … 2020-11-03 2020-10-25 Excel produces the following Summary Output (rounded to 3 decimal places).

If you just want to know the equation for the line of best fit , adding a trendline will work just fine. 2. Next, right click on the trend line and select Polynomial which gives us the second order answers (-0.22, 3.92, 0.82): This trend line is a better fit (R 2 =0.9961). 3. Next, change the Polynomial order to 3 and you get the third order answers (-0.066, 0.476, 1.82, 2.48): This trend line is a slightly better fit: (R 2 =0.9989). Pretty simple Polynomial regression. How can I fit my X, Y data to a polynomial using LINEST?
