[EquisMetaStock Group] Model on optimizing correlation with time delay?

[chichungchoi <no_reply@xxxxxxxxxxxxxxx>]

Does anyone know any model on optimizing correlation for 2 sets of data 
with time delay? It is easy to determine the correlation for 2 sets of 
data without considering time delay, which mean that if I shift the one 
set of data forward / backward as it correlates with other set of data 
or if I select different size of sample for both sets of data, the 
result on correlation could be stronger.  
Does anyone know any model on optimizing the process for correlation?
Thanks in advance for any suggestions
Eric
