Abstract

Smoothing is a branch of regression analysis that allows for a predictor to impact the response as an arbitrary smooth function. It is also known as nonparametric regression. The purpose of this article is to alleviate the restrictiveness of parametric functional relationships, such as that imposed by linearity.

Keywords:

  • splines;
  • kernel smoothing;
  • non parametric regression
