SAS Miner error messages

Are you getting error messages when you ran MBR (Memory Based Reasoning, also known as k-nearest neighbors)?

ERROR in MBR: Run time error was encountered. Please see log for more details.

SOLUTION: Edit variables entering into MBR and unselect all ID attributes like _dataobs_. That should do the trick.

NOTE: MBR processes only interval variables. And it's not sufficient to just change attribute level from binary to interval.

ERROR in Partial Least Squares: No factor was extracted. Use different classifier.

Solution: Use variable selection to reduce the search space.
