Functions for decision trees

The decision tree algorithm is implemented in the DECTREE, GROW_DECTREE, PRUNE_DECTREE, and PREDICT_DECTREE stored procedures. To print decision trees, use the PRINT_MODEL stored procedure.

All stored procedures consist of a mandatory one-string parameter that contains pairs of <parameter>=<value> entries. These entries are separated by a comma. The data type of the parameter is VARCHAR(any).

Valid <parameter>=<value> entries are listed in the parameter descriptions for each stored procedure.
