Diagnosis
Your classification rules may have the consequence that not all objectscan be classified. This can be the case, for example, if the percentagethresholds that you have set do not cover the entire range up to 100percent.

Procedure
Alter your thresholds so that the total range possible is covered up to100 percent. Alternatively, use a class for the remaining objects (thatis, enter in the model parameters a class for all the objects thatcannot be classified in the usual way).
