Nettet24. jun. 2024 · 0. Linear regressions without polynomial features are used very often. One reason is that you can see the marginal effect of some feature directly from the estimated coefficient (s). Say you have a model y i = β 0 + β 1 x i + u i, β 0 and β 1 describe the intercept and slope of a linear function. Nettetsklearn.preprocessing.PolynomialFeatures¶ class sklearn.preprocessing.
