MISSING Subcommand (GENLIN command)

The MISSING subcommand specifies how missing values are handled.

• Cases with system missing values on any variable used by the GENLIN procedure are excluded from the analysis.
• Cases must have valid data for the dependent variable or the events and trials variables, any covariates, the OFFSET variable if it exists, the SCALEWEIGHT variable if it exists, and any SUBJECT and WITHINSUBJECT variables. Cases with missing values for any of these variables are not used in the analysis.
• The CLASSMISSING keyword specifies whether user-missing values of any factors are treated as valid.

EXCLUDE. Exclude user-missing values among any factor or subpopulation variables. Treat user-missing values for these variables as invalid data. This is the default.

INCLUDE. Include user-missing values among any factor or subpopulation variables. Treat user-missing values for these variables as valid data.
