You can use the Method tab to set options in the analysis. (See Figure 26.3.) Each UI control in the tab corresponds to an option in the PRINCOMP procedure. The Rotation tab contains the following controls:
specifies whether the principal components are computed for the correlation matrix or the covariance matrix. This corresponds
to the COV option in the PROC PRINCOMP statement.
specifies how many principal components to compute. This corresponds to the N= option in the PROC PRINCOMP statement. You
can type in this field. If you want five principal components, you can type 5 even though this is not an option in the list.
specifies whether to standardize the principal component score. This corresponds to the STANDARD option in the PROC PRINCOMP
statement. If you clear this option, the scores have variance equal to the corresponding eigenvalue.
