I am trying to use Forest-based classification and regression tool in ArcGIS Pro 2.4.3. My goal is to create a predicted surface using a training datatset (point feature) and explanatory training rasters. All my data is continous. The tool appears to run successfully but my output prediction surface is always empty.

(b) % of overlap between the ranges of the validation data and the training data
(c) % of overlap between the ranges of the training data and the prediction data
* Data ranges do not coincide. Training or validation is occurring with incomplete data.
+ Ranges of the training data and prediction data do not coincide and the tool is attempting to extrapolate.
