I am trying to find a really correlated fingerprint which cross-sectionally describes my population by using 3 omics. For this purpose I have selected block.spls method such is not a supervised analysis. As I do not have an outcome Y, the method suggests to supply an indY which “indicates the position of the matrix response in the list X”. Could someone bettwer explain me, maybe with an example, what does it mean? should I indicate the design matrix?
Hope someone could help me!!
Thank you so much!
