MISSING Subcommand (PARTIAL CORR command)

MISSING controls the treatment of cases with missing values.

• When pairwise deletion is in effect (keyword ANALYSIS), the degrees of freedom for a particular partial coefficient are based on the smallest number of cases that are used in the calculation of any of the simple correlations.
• LISTWISE and ANALYSIS are alternatives. However, each command can be used with either INCLUDE or EXCLUDE. The default is LISTWISE and EXCLUDE.

LISTWISE. Exclude cases with missing values listwise. Cases with missing values for any of the variables that are listed for an analysis—including control variables—are not used in the calculation of the zero-order correlation coefficient. This setting is the default.

ANALYSIS. Exclude cases with missing values on a pair-by-pair basis. Cases with missing values for one or both of a pair of variables are not used in the calculation of zero-order correlation coefficients.

EXCLUDE. Exclude user-missing values. User-missing values are treated as missing. This setting is the default.

INCLUDE. Include user-missing values. User-missing values are treated as valid values.
