MISSING Subcommand (KNN command)
The MISSING
subcommand is
used to control whether user-missing values for categorical variables
are treated as valid values. By default, user-missing values for
categorical variables are treated as invalid.
- The
MISSING
subcommand defines categorical variables as dependent variables withMLEVEL
specificationO
orN
, dependent variables with measurement level set at Ordinal or Nominal in the data dictionary and noMLEVEL
specification, and factors. Scale variables are dependent variables withMLEVEL
specificationS
, dependent variables with Scale measurement level and noMLEVEL
specification, and covariates. - User-missing values for scale variables are always treated as invalid.
- System-missing values for any variables are always treated as invalid.
USERMISSING=EXCLUDE. User-missing values for categorical variables are treated as invalid. This is the default.
USERMISSING=INCLUDE. User-missing values for categorical variables are treated as valid values.
