The function evaluates the matrix of design weights to
predict the response at arbitrary locations x.
This function is not intended to be used directly.
Usage
kernelSx(kernelx="g",X,Xetoile,bx)
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.
Xetoile
Matrix of new design points x* at which to predict the
response variable, size n*, p.
bx
The vector of different bandwidths, length $p$.
Value
Returns the matrix denoted in the paper by $Sx$, n*, n.
