The goal of regression analysis is to model the expected value of a dependent variable y in terms of the value of an independent variable (or vector of independent variables) x. In simple linear regression, the model is used, where ε is an unobserved random error with mean zero conditioned on a scalar variable x. In this model, for each unit increase in the value of x, the co… Nettet3. nov. 2024 · Polynomial regression. This is the simple approach to model non-linear relationships. It add polynomial terms or quadratic terms (square, cubes, etc) to a regression. Spline regression. Fits a smooth curve with a series of polynomial segments. The values delimiting the spline segments are called Knots.

Polynomial regression adds extra independent variables that are the powers of the original variable. Here, we are taking the degree as 2 and hence building a Quadratic regression model.
