Configure Cross Validation Properties
The Cross Validation tab allows you to adjust the Kriging search parameters and other options used for estimating each sample point to better simulate the final estimation run.
Activity Steps
- Select the Cross Validation component in the Project Tree.
- Select the Cross Validation tab in the Property Panel.
- Configure the following options as required.
- Search Angle field group:
- Angle 1 – Search angle in the Z direction for Kriging estimation. Only available if Use Continuity Models is unchecked.
- Angle 2 – Search angle in the X direction for Kriging estimation. Only available if Use Continuity Models is unchecked.
- Angle 3 – Search angle in the Y direction for Kriging estimation. Only available if Use Continuity Models is unchecked.
- Use Continuity Models – Whether to use angles from the associated continuity model.
- Search Range field group:
- Dir 1 – Z direction used to define the search parameters used by the Kriging estimation. Only available if Use Continuity Models is unchecked.
- Dir 2 – X direction used to define the search parameters used by the Kriging estimation. Only available if Use Continuity Models is unchecked.
- Dir 3 – Y direction used to define the search parameters used by the Kriging estimation. Only available if Use Continuity Models is unchecked.
- Use Continuity Models – Whether to use directions from the associated continuity model.
- Samples field group:
- Min – Minimum number of samples used to estimate each point. Default: 2.
- Max – Maximum number of samples used to estimate each point. Default: 100.
- Max Samples per Drill Hole – Whether to set a maximum number of samples per drill hole.
- Use Samples from same Drill Hole – Whether samples from the same drillhole are used to estimate a sample point.
- Use back-transformed results – Allow the cross validation process to run on the raw data, if the variography was done with a normal scores transformation.
- Search Angle field group:
