MISSING Subcommand (NPTESTS command)

The MISSING subcommand controls the treatment of records with missing values.

  [/MISSING [SCOPE={ANALYSIS**}] [USERMISSING={EXCLUDE**}]]
                   {LISTWISE  }               {INCLUDE  }

SCOPE Keyword

The SCOPE keyword specifies how to determine the case basis for tests.

ANALYSIS. Exclude records with missing values on a test-by-test basis. Records with missing values for a field that is used for a specific test are omitted from that test. On subcommands that specify several tests, each test is evaluated separately. This setting is the default.

LISTWISE. Exclude records with missing values listwise. Records with missing values for any field that is named on any subcommand are excluded from all analyses.

USERMISSING Keyword

The USERMISSING keyword is used to control whether user-missing values for categorical fields are treated as valid values. By default, user-missing values for categorical fields are treated as invalid.

• User-missing values for continuous fields are always treated as invalid.
• System-missing values for any fields are always treated as invalid.

EXCLUDE. User-missing values for categorical fields are treated as invalid. This is the default.

INCLUDE. User-missing values for categorical fields are treated as valid values.
