I saw this presentation at the annual SAS JMP conference and really enjoyed it. I had no idea they were videotaping it. It goes through three variaeties of multivariate analysis, PCA, MCA, and MFA, and shows when they may be most useful.
The first part is heavy on the math, which you can skip past if you’re not interested, the rest actually demos a fun use case. This is a topic that a lot of folks struggle with and watching demos of it is always useful. I thought seeing these three techniques side by side could be pretty illuminating.
