localmean_weight | R Documentation |
This function calculates the index values of neighboring points and associated weights required by the local mean variance estimator.
localmean_weight(x, y, prb, nbh = 4)
x |
Vector of x-coordinates for location of the sample points. |
y |
Vector of y-coordinates for location of the sample points. |
prb |
Vector of inclusion probabilities for the sample points. |
nbh |
Number of neighboring points to use in the calculations. |
If ginv fails to return valid output, a NULL object. Otherwise, a
list containing two elements: a matrix named ij
composed of the
index values of neighboring points and a vector named gwt
composed of weights.
