K-fold cross validation leaving partition platform

I was caught off guard by this just wanted to let people know that in JMP 16 you are not able to launch the k-fold cross-validation in the partition platform.  You can still turn it on from preferences and it will auto-launch, but no way to turn it on after the fact.  The workaround is to use Model Screening, but that is only for JMP Pro.  It is rare for a feature to disappear from JMP, but that will be the case with k-fold in partition for JMP 17.

Thanks, @phersh .

Good to know. 

I know Chris G has said in the past that k-fold is NOT recommended for Partition.  So presumably this is why it is being removed.

I've never actually tried it.

Cheers,

Phil

Re: K-fold cross validation leaving partition platform

The preference to turn it on will disappear in v.17? Will it still be available via JSL?

Re: K-fold cross validation leaving partition platform

Hey Nick,  

Here is what I got for tech support on this.

K-fold for Partition is currently still available using scripting or the preference item but will be completely removed in JMP 17.

 

Re: K-fold cross validation leaving partition platform

In prior releases K-Fold in Partition was problematic and didn't really do what it claimed to which caused misleading results.

There is a Wish List entry asking for its return but I believe that is unlikely:Bring back the crossvalidation option in Partition platform menu 

You'll find more details in Defect S0797819.
