Internal Function: Local Mean Variance Neighbors and Weights

Source: R/localmean_weight.R

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)

Arguments

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.

Value

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.
