MISSING Subcommand (DESCRIPTIVES command)

MISSING controls missing values.

• By default, DESCRIPTIVES deletes cases with missing values on a variable-by-variable basis. A case with a missing value for a variable will not be included in the summary statistics for that variable, but the case will be included for variables where it is not missing.
• The VARIABLE and LISTWISE keywords are alternatives; however, each can be specified with INCLUDE.
• When either the keyword VARIABLE or the default missing-value treatment is used, DESCRIPTIVES reports the number of valid cases for each variable. It always displays the number of cases that would be available if listwise deletion of missing values had been selected.

VARIABLE. Exclude cases with missing values on a variable-by-variable basis. This is the default.

LISTWISE. Exclude cases with missing values listwise. Cases with missing values for any variable named are excluded from the computation of statistics for all variables.

INCLUDE. Include user-missing values.
