I am doing PCA in SAS guide. Just wanted to know the following?
Was standardize not required in SAS while performing PCA? As it directly calculates the correlation matrix when I run PCA ( proc princomp)
Kindly advise.
Yes, Proc PrinComp can create a correlation matrix from raw data, so you do not need to standardize the data first.
