Frequently Asked Questions
Quadratic regression fits a second-order polynomial (y = ax² + bx + c) to a set of data points using the least squares method.
At least 3 data points are needed to determine the three coefficients a, b, and c.
R² (coefficient of determination) indicates how well the quadratic model fits the data. A value close to 1 means a good fit.
