But I am facing a problem with it.&nbsp;</P><P>The range, partial sill, nugget, and the RMSE, RMSSE, ASE, give the same value for all four models, i.e., Circular, Spherical, Exponential, and Gaussian. In some cases, it gives 0 partial sill. As the values are the same, it is difficult to get the best-fit model. Kindly help me find the solution.</P> Mon, 17 Nov 2025 08:46:56 GMT VARSHARANIPODDAR 2025-11-17T08:46:56Z https://community.esri.com/t5/arcgis-geostatistical-analyst-questions/geostatistical-wizard/m-p/1666190#M1846 <P>Recently, I used the geostatistical wizard for the water quality analysis.
