Description

Definition of common kernels used in local polynomial estimation.

Usage

	CosK(x)
	EpaK(x)

Numeric vector o value.

Details

The implementation of these kernels is done by means functions that can operate on vectors.

Most common referred numeric values for these kernels are provided as attributes, see RK, mu0K, etc....
