One-Versus-Rest (OVR)  and the One-Versus-One (OVO) LDA

Oct 24, 2024 04:29 AM (902 views)

Hello,

 

I'm looking for a way to test a different LDA strategy than the standard One-off (or hand-out) method when trying to predict a categorical response with multiple classes.

 

I'm particularly interested in the One-Versus-Rest (OVR)  (also referred to as One-Versus-All or OVA)  and the One-Versus-One (OVO) strategies.

 

So, instead of using the default One-off LDA which seeks to solve the classication problem for all classes in the model simultaneously I would like to try testing  OVR strategy (which divides each class into two groups, trans- forming the k-class classi?cation problem into a k − 1 round binary classi?cation problem) and OVO strategy.

 

Any idea how to do this in JMP?

 

Thanks in advance!
