The analysis requires the dependent variable be converted into its
standardized value. This is done using the** descriptive** command using the
**save** option.

descriptives variable = import /save.

Analysis requires calculation of principal component scores. SPSS does not calculate PC scores, rather it uses factor scores. There is a direct linear relationship between the two scores and the standardized regression coefficients are equivalent.
