Polynomial regression with multiple features
WebOct 5, 2024 · A modified implementation of stepwise regression that greedily searches the space of interactions among features in order to build polynomial regression models. Furthermore, the hypothesis tests conducted are valid-post model selection due to the use of a revisiting procedure that implements an alpha-investing rule. As a result, the set of … WebPart 2: Polynomial Regression, and Revisiting the Cab Data ¶. Polynomial regression uses a linear model to estimate a non-linear function (i.e., a function with polynomial terms). For example: y = β 0 + β 1 x i + β 1 x i 2. It is a linear model because we are still solving a linear equation (the linear aspect refers to the beta coefficients).
