IDColumn
Specify the column name that uniquely identifies an observation in test table.
Accumulate
[Optional] Specify the input table column names to copy to the output table.
OutputProb
[Optional] Specify whether the function returns the probability for each response. Only applicable if family of probability distribution is BINOMIAL. The default value is false.
Responses
[Optional] Specify the class labels if the function returns probabilities for each response. Only applicable if the OutputProb element is True. A class label has the value 0 or 1. If not specified, the function returns the probability of the predicted response.
