MISSING Subcommand (QUICK CLUSTER command)

MISSING controls the treatment of cases with missing values.

• LISTWISE, PAIRWISE, and DEFAULT are alternatives. However, each can be used with INCLUDE.

LISTWISE. Delete cases with missing values listwise. A case with a missing value for any of the clustering variables is deleted from the analysis and will not be assigned to a cluster. This is the default.

PAIRWISE. Assign each case to the nearest cluster on the basis of the clustering variables for which the case has nonmissing values. Only cases with missing values for all clustering variables are deleted.

INCLUDE. Treat user-missing values as valid.

DEFAULT. Same as LISTWISE.
