Description

Calculate the bandwidth estimator using various methods.

Usage

Silverman(x)
Silverman2(x)
bw(x, type)

Arguments

x

A vector of data points.

type

One of the following options:

• -1: Silverman's rule of thumb.

• -2: Silverman's adapted rule of thumb.

• >0: The real number is returned without any calculations.

Silverman: Bandwidth estimator based on Silverman's rule of thumb.

Silverman2: Bandwidth estimator based on Silverman's adapted rule of thumb.

bw: Bandwidth estimator based on the selected method.

Examples

set.seed(1)
x <- rnorm(100)
Silverman(x)

Silverman2(x)

bw(x, -1)
