Geostatistical Analyst のライセンスで利用可能。
Some input datasets may have several points with the same x,y coordinates. These points are called coincident points.
The interpolation tools in the Geostatistical Analyst toolbox can use the Coincident points environment variable. By default, the values of coincident points will be averaged.
In kriging models, coincident points are used to estimate the measurement error term when describing the nugget.
メモ:
Radial Basis Functions require a single value at each measurement location, so the option to include all coincident points is not available for these methods.
