Tom F. Wilderjans (nPCA advice)

Dear Maximilian,

regarding your question on cross-validated from last month "Can we decomp a J x J x K array of correlation matrices with Tucker and/or Candecomp/Parafac?"

Yes, INDSCAL is an option. It depends on the specific information that you want to get out of your data whether or not INDSCAL is the optimal choice.

If you need more information or help on the analysis, you can contact me by replying to this email. Please explain a bit more your data (what are the items, how collected) and your research question (what information do you want to get out of the data). I have 10 years experience in analysing three-way data. I probably can give you some advise on how to tackle your problem.
