Hi Jon, A way to do it directly in EM: On your Data Partition node, click on the Variables ellipsis (...). On the menu you can specify a Partition Role as Stratification. e.g. Home Equity IDS->Partition (change Partition Role of 'Reason' from Default to Stratification) I hope this helps, Miguel ...

@friedegg thanks for jumping in! The screenshots take quite some time, very appreciated! I didn't remember the old icons had the "$" sign. Those are so funny. I hope you get to try some of the new stuff soon (ensemble, HPforest, boosting, etc)! Take care, Miguel ... View more

I haven't taken e-learning in a long while, but SAS courses have the solutions for all exercises. Courses are designed so that you can move on even if you miss something. Try to locate the solutions, ideally as an XML that you can import. Do you have the contact for an instructor on the e-learning? Thanks, Miguel ... View more

Hi Elisa, Are you talking about the "Item Constellation Plot"? You can save a bmp file if you do File->Save as. This is useful if you want to take a look at a few items constellation plots. Let's say you are interested in the constellation plots for all your nodes and for the top 3 items with highest weight on the node frequency histogram. I hope this helps, Miguel ... View more

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 ...

Hey mlogan, I am sure you can find a macro to do this on google. And Art Carpenter's book has a macro for EVERYHTING... Carpenter's Complete Guide to the SAS® Macro Language, Second Edition If you don't have a lot of variables just choose a length. Data mymerged; length country $25; merge dataone datatwo; by commonid; run; When you have a chance, take the programming 1 class and this certification: SAS Global Certification: SAS Certified Base Programmer Good luck, Miguel ...

Hey Minal, Enterprise Miner is really easy to learn. Use the reference help a lot (press F1 on your keyboard) and google for white papers on the most common Analytics problems you are trying to solve. Take a look at this thread where we list a good number of ways to do variable selection: . Good luck! Miguel ... View more
