standardization

My thoughts on this is:
Do not trust what SAS say??s and least of all what the Enterprise Miner said.

Robust Statisticians recommendends to standardize using e.g. 
(X - median(X)) / ( MAD(X) / 0.675 ) 

Best,
Matthias

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

Any thoughts on this? Pros Cons
