Missing Value Handling Definition of Missing User-defined missing values are treated as missing in the analysis phase.
Cases Used In the analysis phase, cases with no user- or system-missing values for any predictor variable are used. Cases with user-, system-missing, or out-of-range values for the grouping variable are always excluded.

For the original data, squared Mahalanobis distance is based on canonical functions.
 For the cross-validated data, squared Mahalanobis distance is based on observations.
b. Cross validation is done only for those cases in the analysis. In cross validation, each case is classified by the functions derived from all cases other than that case.
