Although I can set the alpha, I can't see how to directly output the lambda, L1 and L2 values that are used in the chosen models and the resulting R-Sq for the model.

You can script this action or a more specific extraction.</P> Thu, 22 Aug 2024 13:13:27 GMT https://community.jmp.com/t5/Discussions/How-do-I-get-the-value-of-the-R-Sq-L1-L2-and-lambda-out-of/m-p/783411#M96771 Mark_Bailey 2024-08-22T13:13:27Z https://community.jmp.com/t5/Discussions/How-do-I-get-the-value-of-the-R-Sq-L1-L2-and-lambda-out-of/m-p/783602#M96812 <P>Thanks for this Mark, but I can't even find the values in the output to be able to do that. A reply from a JMP technician said "they don't surface these values", which I find a bit hard to understand as surely one wants to be able to see the lambda, L1 and L2 at the very least. Unless they are called by a different name in the JMP output?</P><P>They also said you don't get an R-Sq if you use K-Fold or LOO as validation - but no explanation as to why not - any ideas? I'm pretty sure SAS gives these directly so I'm not sure why JMP is not doing it?</P> Fri, 23 Aug 2024 09:37:16 GMT https://community.jmp.com/t5/Discussions/How-do-I-get-the-value-of-the-R-Sq-L1-L2-and-lambda-out-of/m-p/783602#M96812 gemmahodgson 2024-08-23T09:37:16Z
