Hello-   The Regression node log is not showing a very helpful message, unfortunately.     Sometimes you can force the flow to re-execute in order to clear the error.  Follow these steps:     - Go to the first node in the flow, and change the Rerun property from No to Yes.   - Run the flow.  With Rerun set to Yes, running the flow causes it to re-execute.   - Optionally, change the Rerun property back to no.   If you still get an error, then turn on the MPRINT option, re-execute the flow to create a model package, and send the model package to technical support.  Here are some links with details.     58396 - Specify the MPRINT option in SAS® Enterprise Miner(tm) Project Start Code to display additional diagnostic information in node logs   46764 - Creating a model package (SPK file) in SAS® Enterprise Miner(tm)   41211 - Techniques for testing, solving, or reporting problems that occur when using SAS® Enterprise Miner(tm)   Have a good week! ...
