MISSING Subcommand (ROC ANALYSIS command)

Cases with system-missing values in the test result variable and the actual state variable are always excluded from the analysis. However, the MISSING subcommand allows the user to redefine the user-missing values to be valid.

EXCLUDE

Exclude both user-missing and system-missing values. Cases with a system-missing value or a user-missing value in either the test result variable or the actual state variable are excluded from the analysis. This is the default setting.

INCLUDE

User-missing values are treated as valid. Cases with a system-missing value in either the test result variable or the actual state variable are excluded from the analysis.
