Certain functions or options require that the TD_Analyze external stored procedure and table operators tda_kmeans and tda_dt_calc be installed. To install these UDFs, you must execute the Install or Uninstall UDFs program item in the Teradata Warehouse Miner program group, selecting the option to “Install TD_Analyze Udfs.” This program creates the UDFs by locating the Teradata Client Utility BTEQ. If it exists on the system, you can proceed with the load. Otherwise, an error occurs. The options enabled by the installation of these UDFs include the Fast K-Means clustering option and the Gain Ratio Extreme decision tree option.

See Installing or Uninstalling PMML Scoring UDFs for details about executing the Install or Uninstall UDFs program.
