proc pls : rmse values

Hello Experts,

I would like to retrieve the RMSE with PROC PLS using the PCR method. Is there a specific option in SAS for this?

Thank you !

You can get the PLS equivalent of R-squared* for dependent variables, this is the value shown in Output 92.1.1 here: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.4/statug/statug_pls_examples01.htm

If you really need RMSE I think you could calculate the RMSE if you know the R-squared and total variation in Y, or from the residuals in Y.

* — if there is more than one dependent variable, this quantity is computed across all of the dependent variables.
