The Utilities toolset contains tools for preprocessing and postprocessing of data when developing interpolation models.

Tools in the Utilities toolset

Tool	Description
Compare Geostatistical Layers	Compares and ranks geostatistical layers using customizable criteria based on cross validation statistics.
Cross Validation	Removes one data location and predicts the associated data using the data at the rest of the locations. The primary use for this tool is to compare the predicted value to the observed value in order to obtain useful information about some of your model parameters.
Exploratory Interpolation	Generates various interpolation results from input point features and a field. The interpolation results are then compared and ranked using customizable criteria based on cross validation statistics.
Generate Subset Polygons	Generates nonoverlapping subset polygon features from a set of input points. The goal is to divide the points into compact, nonoverlapping subsets, and create polygon regions around each subset of points. The minimum and maximum number of points in each subset can be controlled.
Neighborhood Selection	Creates a layer of points based on a user-defined neighborhood.
Semivariogram Sensitivity	This tool performs a sensitivity analysis on the predicted values and associated standard errors by changing the model's semivariogram parameters (the nugget, partial sill, and major/minor ranges) within a percentage of the original values.
Subset Features	Divides the original dataset into two parts: one part to be used to model the spatial structure and produce a surface, the other to be used to compare and validate the output surface.
