Quadratic Regression is a process by which the equation of a parabola is found that “best fits” a given set of data. This page is a brief lesson on how to calculate a quadratic regression in Excel. [Round coefficients to the nearest thousandth.] We see that both temperature and temperature squared are significant predictors for the quadratic model (with p-values of 0.0009 and 0.0006, respectively) and that the fit is much better than for the linear fit.From this output, we see the estimated regression equation is \(y_{i}=7.960-0.1537x_{i}+0.001076x_{i}^{2}\).
