 Kernel for nonparametric regression (source code)

= Kernel for nonparametric regression

= Regression kernel
{synonym}

A nonnegative <regression kernel> supplies weights $K((x_i-x)/h)$ in a local <weighted least squares> fit. Unlike a <probability density function>, its integral need not equal one, because rescaling every weight does not change the fitted coefficients.
