MISSING Subcommand (GLM: Univariate command)

By default, cases with missing values for any of the variables on the GLM variable list are excluded from the analysis. The MISSING subcommand allows you to include cases with user-missing values.

• If MISSING is not specified, the default is EXCLUDE.
• Pairwise deletion of missing data is not available in GLM.
• Keywords INCLUDE and EXCLUDE are mutually exclusive.
• If more than one MISSING subcommand is specified, only the last subcommand is in effect.

EXCLUDE. Exclude both user-missing and system-missing values. This setting is the default when MISSING is not specified.

INCLUDE. Treat user-missing values as valid. System-missing values cannot be included in the analysis.
