The model is Guassian and based on event counts. I'm looking at my cross-validation results and noticing that the Root-Mean-Square is 4107.80 and Average Standard Error is 10284.44. According to ESRI, the RMS and ASE should be roughly the same.&nbsp;My question is how do I get the RMS and ASE to be about the same? I've tried removing some of the larger outside block groups but haven't found a good covariance fit.</P><P>I've included the cross validation stats and model summary below. I welcome any advice.&nbsp;</P><P>Thanks,</P><P>SWhatley_3</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="SWhatley_3_0-1701736707944.png" style="width: 544px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/87986i2EC0A25D523A3ECF/image-dimensions/544x328?v=v2" width="544" height="328" role="button" title="SWhatley_3_0-1701736707944.png" alt="SWhatley_3_0-1701736707944.png" /></span></P><P>Below is the summary for model:</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="SWhatley_3_1-1701737136178.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/87988i1714AA5C32AC0387/image-size/medium?v=v2&amp;px=400" role="button" title="SWhatley_3_1-1701737136178.png" alt="SWhatley_3_1-1701737136178.png" /></span></P><P>&nbsp;</P><P>&nbsp;</P><P>&nbsp;</P> Tue, 05 Dec 2023 00:52:09 GMT https://community.esri.com/t5/arcgis-pro-questions/aerial-interpolation/m-p/1356667#M75882 SWhatley_3 2023-12-05T00:52:09Z https://community.esri.com/t5/arcgis-pro-questions/aerial-interpolation/m-p/1358384#M76108 <P>I've attached a zip file of a geodatabase containing the block groups feature class, the interpolation layer.
