AttrTableGroupByColumns

Specify the names of the columns on which AttributeTable is partitioned. Each partition contains one attribute of the input data.

AttrTablePIDColumns

Specify the names of the AttributeTable columns that define the data point identifiers.

AttrTableValColumn

Specify the name of the AttributeTable column that contains the input values.

OutputProb

[Required to be 'true' with Responses, optional otherwise.] Specify whether to output the probability for each response.

To use this syntax element with DecisionTreePredict_MLE, you must have used it with the DecisionTree call that output the Model table.

Default: 'false'

Responses

[Optional with OutputProb, disallowed otherwise] Specify the labels for which to output probabilities.

To see all labels, use either of the following queries. ResponseTable, response_column, and output_table are from the DecisionTree function call that output the model_table for this function. ResponseTable is an input table, response_column is the ResponseColumn syntax element value, and output_table is the OutputTable syntax element value.

SELECT response_column FROM ResponseTable;

SELECT prob_label_order FROM output_table SAMPLE 1;

Default behavior: Output only the probability of the predicted class.

Accumulate

[Optional] Specify the names of the AttributeTable columns to copy to the output table.
