A scoring catalog is a specialized LityxIQ dataset which holds the output of scoring jobs. The output of scoring jobs is usually comprised of scores and/or groups (such as deciles), along with a unique ID for each scored record.
In Predict, scoring catalogs can be created and managed within the Scoring Catalogs area.
Because scoring catalogs are simply datasets, once they are created, they can also be viewed and managed in the Data Manager. By default, they will appear in the automatically created dataset library named "Scoring Catalogs", but optionally you can place the catalog in any dataset library at the time it is created.
