MISSING Subcommand (AIM command)

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

• A case is never used if it contains system-missing values in the grouping variable, categorical variable list, or the continuous variable list.
• If this subcommand is not specified, the default is EXCLUDE.

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

INCLUDE . User-missing values are treated as valid. Only system-missing values are not included in the analysis.
