Cause of the message

When you perform binary or multiclass classification on a variable that you want to predict, the prediction model will fail if it contains values that exceed the criteria.

Solution

For binary classification

Make sure that the column for the variable you want to predict does not contain more than two types of values, and then modify the prediction model creation (training) data so that it contains only two types.
If there are more than 1000 rows in the file, sort the data so that all types of data appear before the 1000 row.

For multiclass classification

When using multiclass classification as the prediction type, Easy Predictive Analytics allows for a maximum 200 types of classification.
Make sure that the column for the variable you want to predict does not contain more than 200 types, and correct the prediction model creation (training) data to only contain 200 types.
