OraPredictTask
used to produce predictions for the specified target column in the input dataset as predictions output table. The input consists of a table that has case id column, other predictor columns and a target column. The target column containing the values to predict. The input data must contain some cases in which the target value is known (that is, is not NULL). Cases where the target values are known are used to train models.
Predictions output table has the following fixed columns:
Predictions are returned for all cases in the input data. Predicted values for known cases may be interesting in some situations, for example, to perform deviation analysis, that is, to compare predicted values and actual values.
