In HaotianXu/changepoints: A Collection of Change-Point Detection Methods

Multivariate kernel density estimation based on Triweight kernel.

Description

Perform multivariate kernel density estimation and evaluated the estimated densities at specified points.

Usage

kde.triwei.eval(x, bw, eval.points)

Arguments

x	A numeric matrix of observations with horizontal axis being dimension, and vertical axis being time.
eval.points	A numeric matrix of evaluated data points with horizontal axis being dimension, and vertical axis being time..
h	A numeric scalar of bandwidth parameter.

Value

A numeric vector of evaluated densities.

Examples

n = 100
p = 10
x = matrix(rnorm(n*p), nrow = n)
h = 2*(1/n)^{1/(4+p)} # bandwith
kde.triwei.eval(x, h, x)
