SPLS is a supervised method or unsupervised method?

Analysis

Hi all,

I am new to statistic and trying to do data integration with sPLS.

One thing I am confusing is that I am not sure whether sPLS is supervised or unsupervised. here Selecting your Method | mixOmics it announced that it is supervised or unsupervised. and here in the case study, sPLS Liver Toxicity Case Study | mixOmics, it announced that it is unsupervised. So is anyone clear about supervised or unsupervised?

Best regards,
Xin

hi @xin

The supervised refers to classification or regression. PLS can do either regression, or no regression with a canonical mode. There are many variants of PLS.

In the liver toxicity study this is a typo, by ‘unsupervised’ we meant: no classification (in that example you will do a regression).

Hi Kim,

Thanks for your reply! Just want to make a confirmation. If I use sPLS with “regression” mode for data integration. It is “supervised”. And “canonical” mode is “unsupervised”. right?

Sorry for this question, I am not very familiar with statistic.

Thanks!
Xin

hi @xin

Yes your interpretation is correct. Our handbook might explain this a bit better.
