Observations with missing values for variables in the analysis
are excluded from the development of the classification criterion.
When the values of the classification variable are missing, the
observation is excluded from the development of the classification
criterion, but if no other variables in the analysis have missing
values for that observation, the observation is classified and
displayed with the classification results.
