dij {HQM} | R Documentation |
D matrix entries, used for the implementation of the local linear kernel
Description
Calculates the entries of the D
matrix in the definition of the local linear kernel
Usage
dij(b,x,y, K)
Arguments
x |
A vector of design points where the kernel will be evaluated. |
y |
A vector of sample data points. |
b |
The bandwidth to use (a scalar). |
K |
The kernel function to use. |
Details
Implements the caclulation of all d \times d
entries of matrix D
, which is part of the definition of the local linear kernel. The actual calculation is performed by
d_{jk} = \sum_{i=1}^n \int_0^T K_b(x-X_i(s))\{x-X_{ij}(s)\}\{x-X_{ik}(s)\} Z_i(s)ds,
Value
scalar value, the result of d_{jk}
.
