Subject:      segmenating data set
Content-Type: text/plain

Suppose I have a data set that contains dependent variable DEPVAR, and
30 independent variables VAR1-VAR30. I want to segment that data set
into several subsets and model DEPVAR on those subsets seperately in
order to get the highest predictiveness. Is there a sound methodology of
segmentation based on statistical test, instead of ad hoc knowledge of
variables in the data set?
 
Thanks very much for any response.
