2. when i run proc varclus i write option of tree. at the end i want to know which variable at what cluster? how i know it? what i need write in procedure to get this?

Re: proc varclus

1. Proc Cluster -> clusters observations together

Proc VarClus -> clusters variables together. 


2. Capture the ODS table

Check the structure of OutTree dataset. Not sure if it's one of those that can be used or only contains data for Proc tree.
