MISSING Subcommand (LOGISTIC REGRESSION command)

LOGISTIC REGRESSION excludes all cases with missing values on any of the independent variables. For a case with a missing value on the dependent variable, predicted values are calculated if it has nonmissing values on all independent variables. The MISSING subcommand controls the processing of user-missing values. If the subcommand is not specified, the default is EXCLUDE.

EXCLUDE. Delete cases with user-missing values as well as system-missing values. This setting is the default.

INCLUDE. Include user-missing values in the analysis.
