- Reciprocal: the mean of the values, weighted by the inverse of their distance from the target point. If one of the geopoints lies exactly on the target point then its value is used directly and the rest of the values discarded.
Exponential Mean: computes the mean of the values weighted (multiplied) by the following:
if Threshold is not zero:
Mathinline e^{-distance/tolerance^2}- if Threshold is zero: 1 if the point is on the target point, 0 otherwise
- note that this method, combined with setting Threshold to zero computes the proportion of points which lie exactly on the target point
- Exponential Sum: performs the same computation as Exponential Mean, but does not finally divide by the total weight. With a Threshold of zero, this method will compute the number of input points that lie exactly on each target point.
