The higher the exponent, the more numerous the curves. What is the polynomial regression model? A polynomial model is a form of regression analysis. We use an N-th degree polynomial to model the relationship between the dependent variable y and the
Polynomial regression is a technique we can use when the relationship between a predictor variable and a response variable is nonlinear. This type of regression takes the form: Y = β0 + β1X + β2X2 + … + βhXh + ε where h is the “degree” of the polynomial.

However, polynomial regression models may have other predictor variables in them as well, which could lead to interaction terms. So as you can see, the basic equation for a polynomial regression model above is a relatively simple model, but you can imagine how the model can grow depending on your situation!

• This is just the linear multiple regression model – The linear regression model y = X + is a general model for fitting any relationship that is linear in the unknown parameter . Polynomial regression model:.
You can fit the following linear, quadratic, or cubic regression models: Model type Order Statistical model; linear : first : If linear regression is used only for the previous sample, the resulting model is shown in Figure 1 (code implementation omitted here): The training model is very simple, but it can not fully express the relationship between data, which is underfitting. If polynomial regression is used, the code is as follows: Spline regression. Polynomial regression only captures a certain amount of curvature in a nonlinear relationship. An alternative, and often superior, approach to modeling nonlinear relationships is to use splines (P. Bruce and Bruce 2017). Splines provide a way to smoothly interpolate between fixed points, called knots. Polynomial regression comes into play when your correlation of data is nonlinear and thus a linear model type isn't fitting anymore.
