MISSING Subcommand (RELIABILITY command)

MISSING controls the deletion of cases with user-missing data.

• RELIABILITY deletes cases from analysis if they have a missing value for any variable named on the VARIABLES subcommand. By default, both system-missing and user-missing values are excluded.

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

INCLUDE. Treat user-missing values as valid. Only system-missing values are excluded.
