Partial Correlations Options
Statistics. You can choose one or both of the following:
- Means and standard deviations. Displayed for each variable. The number of cases with nonmissing values is also shown.
- Zero-order correlations. A matrix of simple correlations between all variables, including control variables, is displayed.
Missing Values. You can choose one of the following alternatives:
- Exclude cases listwise. Cases having missing values for any variable, including a control variable, are excluded from all computations.
- Exclude cases pairwise. For computation of the zero-order correlations on which the partial correlations are based, a case having missing values for both or one of a pair of variables is not used. Pairwise deletion uses as much of the data as possible. However, the number of cases may differ across coefficients. When pairwise deletion is in effect, the degrees of freedom for a particular partial coefficient are based on the smallest number of cases used in the calculation of any of the zero-order correlations.
