I understand that because the assumption of normality does not hold for this kind of data, I cannot proceed with a regular PCA. I checked out what I could find in the internet, and the most recent and useful treatment seems to be Brady's 1990 article "Dimensional Analysis of Ranking Data" in the American Journal of Political Science 34:1017-48. However, I cannot translate his point into a work-flow in SPSS.
I am looking for help in how I can go about analyzing this data in terms of dimensions. Please contact Julia Eksner with a quote for your hourly wage at firstname.lastname@example.org.
