Cross-validation for 10 groups

SASdevAnneMarie — Sun, 03 May 2026 13:07:16 GMT

Hello Experts,

I'm wondering if, for performing 10-fold cross-validation with the proc pls method=pcr method, I should use cv=split(10) cvtest(seed=12345)?

Thank you for your help!

I think "cv=split(10)" is good enough.

and I quoted:

CV=TESTSET(SAS-data-set)
specifies a test set of observations to be used for validation (formally, this is called “test set validation”
rather than “cross validation”).

or using "CV=ONE" or "CV=BLOCK(10)"
