Model scoring in TWM is performed entirely through generated SQL, executed in the database (although PMML based scoring generally requires that certain supplied User Defined Functions be installed beforehand). A scoring analysis is provided for every Teradata Warehouse Miner algorithm that produces a predictive model (thus excluding the Association Rules algorithm).
Scoring applies a predictive model to a data set that has the same columns as those used in building the model, with the exception that the scoring input table need not always include the predicted or dependent variable column for those models that utilize one. In fact, the dependent variable column is required only when model evaluation is requested in the Tree Scoring, Linear Scoring and Logistic Scoring analyses.
