<model name>_DISCRETE_STATISTICS table

This table contains statistical information about the values of active categorical columns and active continuous columns with 100 values or less for each node.

The content of this table depends on the value of the statistics parameter when the model is built. If you specify statistics=none or statistics=columns, this table contains only statistics for the target column values in each node.

The following table shows the table columns:

Table 1. Columns of the <model name>_DISCRETE_STATISTICS table
Column Data type Description
NODEID BIGINT Index value of the node in the tree model

The root node has the NODEID 1.

COLUMNNAME VARCHAR(128) Name of the input column
VALUE VARCHAR(512) Value that is contained in COLUMNNAME

If the column is numeric, the value is a string representation of the value of the true column.

COUNT DOUBLE Number of occurrences of records in the VALUE column
RELFREQUENCY DOUBLE Percentage of occurrences of records in the VALUE column

The relative frequency is based on all records, where records with invalid values or NULL values are included.

DEVIATION DOUBLE RELFREQUENCY(NODEID) -RELFREQUENCY(1)
