Hello,

 

I am trying to find some correlations between 11 variables (10 continuous variables (with 2 not normally distributed) and 1 categorial variable (1, 2, 3 or 4)). For that, I would like to start with a descriptive analysis using PCA. Regarding the kind of variables (and distributions) I have, I would like to perform a PCA using a matrix of Spearman's correlation. I have seen that we can do it with R software but I'm using SAS and I don't find any information about it, how to do it...

Do you have any idea of how I can do it (in which statement, syntax).

 

Thank you very much.

 

Sophie

Look into PROC PRINCOMP and/or PROC FACTOR.
