The Variables Tab

You can use the Variables tab to specify the numerical variables for the analysis. The Variables tab is shown in Figure 27.3.

The variables in the Y Variables list correspond to variables in the VAR statement of the FACTOR procedure.

The Partial list is rarely used. The variables in this list correspond to variables in the PARTIAL statement of the FACTOR procedure. The FACTOR procedure computes the factors for the residuals of the Y variables after regression on the PARTIAL variables. Equivalently, the factors are determined by the partial correlation matrix between the Y variables, controlling for the PARTIAL variables.
