    n predictive analytics the user decides for the attribute (column/feature) that predictions should be made for - the target attribute. A model is then trained with records that have values for that attribute - the training data set. The model can then be used for new records where the value of the target attribute is unknown, to predict that value. That's why in predictive analytics there is a training/learning step (on historic data) and a scoring/prediction step (on new data).
