Dear Anjan

I'd be interested to hear what literature that is.
If your statement were correct, then all normalisation methods should 
just be replaced by ACE (as has indeed been proposed, see Pubmed-ID 
14633397, Faller et al., Normalization of DNA-microarray data by 
nonlinear correlation maximization.)
