Polynomial Regression Calculator
Here we've got a quadratic regression, also known as second-order polynomial regression, where we fit parabolas. Degree 3: y = a 0 + a 1 x + a 2 x 2 + a 3 x 3. This is cubic regression, a.k.a. third-degree polynomial regression, and here we deal with cubic functions, that is, curves of degree 3.
