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
