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 CLASSMISSING keyword on 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 is excluded from the analysis. This is the default setting.

INCLUDE
