Polynomial regression using statsmodel - Prasad Ostwal
WebNow you want to have a polynomial regression (let's make 2 degree polynomial). We will create a few additional features: x1*x2, x1^2 and x2^2. So we will get your 'linear regression': y = a1 * x1 + a2 * x2 + a3 * x1*x2 + a4 * x1^2 + a5 * x2^2. This nicely shows an important concept curse of dimensionality, because the number of new features ...
