Grouping objects by clustering to improve predictive modeling

Hi,

I'm doing a predictive modeling in SAS Ent. Min., and I'm trying do the observation grouping to improve the predictive models. So basically what I can't do and really would be great if smb could help, s this.... I did a clustering of my huge data set, I get 5 clusters, so now what I would like to do is to analyse just 2 cluster, but I can't extract those 2 clusters into datasets. I've tried ith SAS code node, and doing it with &EM_metasource_class; &EM_IMPORT_CLUSMEAN and &EM_IMPORT_CLUSSTAT but its not working...so if you have any suggestions...well I just can't wait to learned them:)

Hey Kasiacie,

You are on the right track

One way to do it.

On your code node use the below to:

-library statement. you can put this subset data on your own library. or if you prefer to do further analysis use &em_export_train (commented out below).

-data step code..

libname d "d:\";

*/data &EM_EXPORT_TRAIN/;*
data d.mycluster2;
set &EM_IMPORT_DATA;
where _segment_=2;
run;

I hope this helps,

Miguel
