11_discrete_kernels: Discrete Kernels

Description

Discrete kernels (without standardized intervals), for discrete kernel smoothing.

NOTE THAT THESE MAY BE REMOVED.

Usage

binomial.dkernel (bw)

Arguments

bw

Integer, the bandwidth. This should be a positive odd number. (Even numbers are rounded up).

Value

A dkernel object.

Details

NOTE THAT THESE MAY BE REMOVED.

This is a constructor for a binomial kernel object.

Currently, this object is a named list (with pmf and cdf components).

Here, the PMF is symmetric about zero (in contrast to how a binomial distribution is normally defined), and has zero-probability outside the interval [-hbw, hbw], where: hbw = (bw - 1) / 2

This object is used inside discrete kernel smoothing. (In which case, you provide the constructor, not the object).
