Hi, I wanna do cluster analysis for my categorical variable. I have different five variables which, each of them, are rated based on 1-5 rating scale. (1 lowest and 5 highest). Can I run cluster analysis for this data? If yes, do I have (can) do them together or I have to (can) do it separately? Which is the best tool to do it? Is that "Cluster and Out liars" or "Hot spot analysis" tool?
