poids {ibr}

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
