Handling overlapping in classification models

[sammmy]

Please can anyone help on how to identify if my data is having heavy overlap in classification and how to handle overlapping.

I have done that for class imbalance but I suspect my data is also suffering from class overlapping.

SAS offers many classification tools (e.g. DISCRIM, SPLIT, CLUSTER, FMM). What are you using, and how?
