<model name>_NUMERIC_STATISTICS table

This table contains statistical information about the values of active continuous columns with more than 100 values for each node.

The contents and the existence of this table depend on the value of the statistics parameter when the model is built. If you specify statistics=values:n or statistics=all, this table is created. It then contains statistics for active continuous columns with more than n (default 100) distinct values for each node.

The following table shows the table columns:

Table 1. Columns of the <model name>_NUMERIC_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 numeric input column
FROMVALUE DOUBLE Lower interval boundary

A value of NULL indicates negative infinity.

TOVALUE DOUBLE Upper interval boundary

A value of NULL indicates positive infinity.

CLOSURE VARCHAR(12) Indicates whether the interval limits are contained

Possible values are openClosed, openOpen, closedOpen, and closedClosed.

COUNT DOUBLE Number of occurrences of records in the interval
RELFREQUENCY DOUBLE Percentage of occurrences of records in the interval

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

DEVIATION DOUBLE RELFREQUENCY(NODEID) -RELFREQUENCY(0)
MEAN DOUBLE Mean of all values in the interval
VARIANCE DOUBLE Variance of all values in the interval
