Default Missing Value Treatments

Use this selection to generate recommended missing value treatments based on the mining algorithm that you plan to use.

If you invoke this wizard from a Mining Activity, the appropriate default treatments are specified automatically.

Click the radio button opposite the algorithm that you plan to use for mining, and click OK. (The algorithms listed are the ones that require missing values treatment.) Oracle Data Mining tells you that the existing treatments will be deleted and replaced with the new ones (the recommended ones). Click Yes to delete the old treatments and replace them with the new ones or No to cancel the changes.

If you select Other (the default when this wizard is not invoked from a mining activity), there is no default treatment.
