The Variables Tab

You can use the Variables tab to specify the numerical variables for the analysis. The Variables tab is shown in Figure 26.2.

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

The Partial list is rarely used. The variables in this list correspond to variables in the PARTIAL statement of the PRINCOMP procedure. The PRINCOMP procedure computes the principal components of the residuals from the prediction of the VAR variables by the PARTIAL variables.
