K-fold cross validation leaving partition platform

Question

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.

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.

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.

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