MISSING Subcommand (OPTIMAL BINNING command)

The MISSING subcommand specifies whether missing values are handled using listwise or pairwise deletion.

• User-missing values are always treated as invalid. When recoding the original binning input variable values into a new variable, user-missing values are converted into system-missing values.

SCOPE = PAIRWISE | LISTWISE. Missing value handling method. LISTWISE provides a consistent case base. It operates across all variables specified on the VARIABLES subcommand. If any variable is missing for a case, then the entire case is excluded.

PAIRWISE makes use of as many valid values as possible. When METHOD = MDLP, it operates on each guide and binning input variable pair. The procedure will make use of all cases with nonmissing values on the guide and binning input variable. When METHOD = EQUALFREQ, it uses all cases with nonmissing values for each binning input variable. PAIRWISE is the default.
