MISSING Subcommand (MIXED command)

The MISSING subcommand specifies the way to handle cases with user-missing values.

• If this subcommand is not specified, the default is EXCLUDE.
• Cases, which contain system-missing values in one of the variables, are always deleted.
• The keywords EXCLUDE and INCLUDE are mutually exclusive. Only one of them can be specified at once.

EXCLUDE. Exclude both user-missing and system-missing values. This is the default.

INCLUDE. User-missing values are treated as valid. System-missing values cannot be included in the analysis.
