Output Table Schema

Each row of the table represents one observation.

Column Data Type Description
id INTEGER Row (observation) identifier.
prediction VARCHAR Prediction for observation.
loglik DOUBLE PRECISION [Appears only without Responses syntax element.] Loglikelihood that observation belongs to class label in prediction column.
prob DOUBLE PRECISION [Appears only when you both specify OutputProb ('true') and omit Responses.] Probability that observation belongs to class label in prediction column, which is max(softmax(loglik)).
loglik_response DOUBLE PRECISION [Appears only with Responses syntax element. Column appears once for each specified response.] Loglikelihood (natural logarithm of probability) that observation belongs to class response.
prob_response DOUBLE PRECISION [Appears only when you specify both OutputProb ('true') and Responses. Column appears once for each specified response.] Probability that observation belongs to class response, which is calculated as follows:

softmax(loglik_response)
