Unbalanced data

FR60 — Wed, 19 Apr 2017 09:41:22 GMT

I'm interested in analysis of unbalanced data set (for example with 5% of target and 95% remaining..). Is there in JMP13 (not PRO) any feature like SMOTE or MSMOTE to balance the groups?

Thanks. Felice

JMP does have a stratify option when creating a subset of from a given table. Go to Tables > Subset. Select Random and whatever portion of your data you want sample from and then check Stratify.
