Note that the “local constant” type of regression provided here is also known as Nadaraya-Watson kernel regression; “local linear” is an extension of that which suffers less from bias issues at the edge of the support(...)

- The kernel regression is a non-parametric technique in statistics to estimate the conditional expectation of a random variable. The objective is to find a non-linear relation between a pair of random variables X and Y.
In any nonparametric regression, the conditional expectation of a variable [math]\displaystyle{ Y }[/math] relative to a variable [math]\displaystyle{ X }[/math] may be written:
[math]\displaystyle{ \operatorname{E}(Y | X) = m(X) }[/math]
where [math]\displaystyle{ m }[/math] is an unknown function.
