MISSING Subcommand (DISCRIMINANT command)

MISSING controls the treatment of cases with missing values in the analysis phase. By default, cases with missing values for any variable named on the VARIABLES subcommand are not used in the analysis phase but are used in classification.

• The keyword INCLUDE includes cases with user-missing values in the analysis phase.
• Cases with missing or out-of-range values for the grouping variable are always excluded.

EXCLUDE. Exclude all cases with missing values. Cases with user or system-missing values are excluded from the analysis. This is the default.

INCLUDE. Include cases with user-missing values. User-missing values are treated as valid values. Only the system-missing value is treated as missing.
