You asked another question about clustering, so I presume you want to standardize some variables before clustering. In SAS, PROC STDIZE offers 18 standardization methods. See for details. If you're really concerned about this I would suggest running simulations to compare the performance of various standardization methods (relative to your data and what you're after).

SAS Enterprise Miner recommendeds to standardize using X / STDEV(X) versus [X mean(X)] / STDEV(X)

Any thoughts on this? Pros Cons
