Reading PLS Output

Hi, I am using the PROC PLS and I can't figure out how the x and y scores are calculated. Could anybody help me?

Hi:
In Enterprise Guide, if you go to [pre]
Help --> SAS Enterprise Guide Help
click on the Search tab and then type
"Regression Methods" PLS
into the Search field
then, click Display
[/pre]
One of the hits that comes up, should be entitled "Regression Methods" with a location of SAS System Documentation. If you open that topic, you will see that it is a description of how the score vector is calculated, depending on your different models and methods.

If you do not have the SAS Documentation available to you on your installation, then you can find out how to access SAS on-line documentation at this site:
http://support.sas.com/documentation/onlinedoc/index.html

If you have other, more technical or statistical, questions about PROC PLS, you should probably contact Tech Support:

Good luck!

Me again. We couldn't replicate the scores using weights matrices as we understood from SAS help.

Have anyone tried sometime to manually calculate factor scores for both dependent and independent variables by using the EST outpult dataset?

Thanks,
Diego.
