MISSING Keyword (GGRAPH command)

The MISSING keyword specifies how missing values are handled when the variable specification includes an aggregation function. When the variable specification includes only variables or includes the CASEVALUE function, this keyword does not affect the treatment of missing values. The graph dataset is unaggregated, so cases with system- and user-missing values are always included in the graph dataset.

LISTWISE. Exclude the whole case if any one of the variables in the variable specification has a missing value. This is the default.

VARIABLEWISE. Exclude a case from the aggregation function if the value is missing for a particular variable being analyzed. This means that a case is excluded if that case has a missing value for a variable that is a summary function parameter.
