I have a project that I am trying to classify a rare event and so would like to experiment with boosting and bagging following the example laid out in this article, https://support.sas.com/resources/papers/proceedings14/SAS133-2014.pdf

The problem is that when I set up my project diagram in a similar manner as on page 3 and try to run the process flow I get a run time error as soon as EM tries to process the first start group node. I have posted the output from the log file below. Any help would be greatly appreciated.

Hey Josh,

Glad you are giving the Start/End Group nodes a try!

I could not find an error in your log.

Let's troubleshoot a bit. Try the same flows as in page 3 with HMEQ data set.

To generate HMEQ go to Help->Generate Sample Data->Home Equity.

Then create a flow like Start Groups(Mode=Bagging)->Tree->End Groups.

Does that work now?

99% of the time I forget to specify bagging or boosting as the mode. It might be something else in your case though.

Thanks,

Miguel

Thanks for the reply.  I ran the home equity data and it worked perfectly.  I think the problem was that instead of using a sas data table as my data source, I was using the file import node.  I went back and turned my csv data file into a sas data table in enterprise guide, then imported into EM and it works fine.  Why is this a problem?

M_Maldonado
Barite | Level 11

not sure why would that be a problem. I will give it a try with the File Import node and keep you posted.

good luck with your ensemble models!

I had a similar experience. Using the File Import node with a CSV file failed. So I opened the CSV file with Excel, set the format of each column appropriately, and imported it to our SAS server. Using the Data Input node, bagging worked as advertised. Fantastic!

JPW,

Also we should be looking at the log of the node that errored out.

Right click on that node and click on Results. Once they open go to View->SAS Results->Log.

Thanks,
