https://communities.sas.com/t5/ODS-and-Base-Reporting/PLS-procedure/m-p/1152#M539 I have a question about the PLS procedure. If a have a table with standardized variables and run the PLS procedure with method=PCR, CV=one and CVTEST(stat=PRESS). Why do a get different PRESS values if I run it with and without the nocenter and noscale command specified?<BR /> <BR /> Cheers Marcus Thu, 27 Jul 2006 07:33:33 GMT marcus 2006-07-27T07:33:33Z https://communities.sas.com/t5/ODS-and-Base-Reporting/PLS-procedure/m-p/1152#M539 I have a question about the PLS procedure.
