Variable clustering node

VanDalucas — Tue, 12 Jul 2016 12:33:04 GMT

Hi,

I try to run this path in Enterprise Miner 13.2 to get rid of correlated variables:

Dataset --> Metadata --> Transform variables --> Sample (becouse sample size>100000) --> Variable clustering

but I get a run-time error on variable clustering node prompting me to see at the log file where I find no description of the error..

any idea?

Thank you

Just want to make sure you are looking at the correct log - are you opening the Results of the Variable Clustering node and viewing the log from there (View>SAS Results>Log) ? From there, you should be able to search for "ERROR:" to find more information.

Hi, thank for the reply

The Run Status window pops up and notifies me over a run time error before any results are produced. Log tab next to diagram tab is empty, Project Log (View --> Project Log) does not produce anything

That's right, the diagram and project logs wouldn't show the error message. So after running and getting the error window at a particular node, right-click on the node and select Results... and then click on View --> SAS Results --> Log For some nodes, the log might be truncated in the node itself but it will tell you at the bottom of the log where the full log is in those situations.

it is!

I though you meant the results windows that was supposed to pop up if everything had run successfully

So thanks a lot!

The problem is at the TRANSFORM VARIABLES node that preceded the VARIABLES CLUSTERING NODE. The settings for this node was: DEFAULT METHODS,INTERVAL INPUTS --> RANGE. Whenever I change the first setting to NONE the path runs successfully no matter what the other setting were. Some other methods produce the same problem (like BUCKET) while others don't (like LOG)

Thanks a lot

The Variable Clustering node only works on interval inputs, so when you use a binning transformation like Bucket, the interval inputs are converted to nominal, so it won't run. Though I'm not sure why that would happen with the Range transformation.
