poids

Product kernel evaluation

Description

Evaluate the product of kernel function at (X-valx)/bx: Gaussian, Epanechnikov, Uniform, Quartic. This function is not intended to be used directly.

Usage

poids(kernelx,X,bx,valx,n,p)

Arguments

`kernelx`	Character string which allows to choose between gaussian kernel (`"g"`), Epanechnikov (`"e"`), uniform (`"u"`), quartic (`"q"`).
`X`	Matrix of explanatory variables, size n, p.
`bx`	The vector of different bandwidths, length p.
`valx`	The vector of length p at which the product kernel is evaluated.
`n`	Number of rows of X.
`p`	Number of columns of X.

Value

Returns a vector which coordinates are the values of the product kernel at the given coordinate
