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.
