Cause of the message

Easy Predictive Analytics automatically removes rows from the prediction model creation (training) data that are missing (empty) for the variable to be predicted. If a sufficient amount of data is not obtained as a result of removal, it may not be possible to proceed with learning.

Solution

For rows where the variable you want to predict is missing (empty), enter the value of the variable you want to predict. Alternatively, add data that does not have missing values for the variable to be predicted to the prediction model creation (training) data.
