Hi Collegues, I have 750 variables related to customers’ transaction behavior, account balances etc. I have reduced the number of variables using proc varclus. Then the representative variables in each cluster  were inputted into proc logistic to identify predictors that are associated with acquisition of bank products. I have two specific questions. 1.       Should I standardize the input variables separately before inputting into proc varclus? 2.       I used the following statements. Is there any method that I can use so that I do not need to list down the name of all 750 variables? proc varclus data=temp.dataset               outtree=tree      centroid                maxclusters=25; var         a     b     c     d      e..............................................name of 750th variable ; run; Would really appreciate any ideas.
