# Nonparametric Regression Algorithm

(Redirected from Nonparametric Regression)

A Nonparametric Regression Algorithm is a regression algorithm that does not require a parameterized regression model as an input.

**Context:**- It can (often) infer Distribution Functions from the Input Dataset.
- It can be implemented by Nonparametric Regression System (to solve a non-parametric regression task).

**Example(s):**- an Additive Model, such as a generalized additive model.
- Kernel Regression.
- MARS algorithm.

**Counter-Example(s):****See:**Regression Tree Training Algorithm.

**Nonparametric regression**is a form of regression analysis in which the predictor does not take a predetermined form but is constructed according to information derived from the data. Nonparametric regression requires larger sample sizes than regression based on parametric models because the data must supply the model structure as well as the model estimates.

- ABSTRACT: In general, there will be visible differences between a parametric and a nonparametric curve estimate. It is therefore quite natural to compare these in order to decide whether the parametric model could be justified. An asymptotic quantification is the distribution of the integrated squared difference between these curves. We show that the standard way of bootstrapping this statistic fails. We use and analyse a different form of bootstrapping for this task. We call this method the wild bootstrap and apply it to fitting Engel curves in expenditure data analysis.
