For instance, consider an example in which p = 100 and β 1 = β 2 =... = 0 is true, so no variable is truly associated with the response.

Choosing the Correct Type of Regression Analysis

WebHastie and Tibshirani defines that linear regression is a parametric approach since it assumes a linear functional form of f (X). Non-parametric methods do not explicitly assume the form for f (X). This means that a non-parametric method will fit the model based on an estimate of f, calculated from the model.
