Quadratic regression
QuestionThe data is fitted by linear and quadratic regression. First, find a linear regression equation for the $n$ data points, $20 \le n \le 35$.
They then are shown that the quadratic regression is often a better fit as measured by SSE. Also users can experiment with fitting polynomials of higher degree.
