I have done a principal component analysis using SPSS and now have 3 components. 2 components have 4 items in the subscale, and 1 component has 3 items. Component scores using regression for each factor were added as variables to the data set by SPSS.
My question is: can the component scores (the new variables that SPSS added to the data set) be used as the variables for K-means cluster analysis to form clusters? My aim is to find out the exact number of cases in each factor, which I intend to do through cluster analysis. Is this the statistically correct method? Thank you for any input.
