The error propagation model is ArcGIS Modelbuilder has a
number of advantages. First, it presents a very intuitive and visual
interface to developing and using a model, which makes it easier
to follow for those who are new to this type of modeling. Very
limited scripting or programming experience is required. Second,
the model is fully extendible – specific parameters can be
modified by the user and specific model elements can be replaced
or updated. For example, modifying the spatially autocorrelated
error model is relatively simple for those with Modelbuilder
skills. Finally, the model can easily be shared with the broader
ArcGIS user community. The model itself can be copied and any
of its elements can be modified and run within ArcGIS.
