Usage Note 20054: "ERROR: Maximum levels of 512 exceeded"
By default, SAS® Enterprise Miner™ limits the maximum number of levels of a
nominal variable to 512. If you exceed this limit, a message is displayed:
ERROR: Maximum levels of 512 exceeded.
This error does not necessarily mean that there is a problem. If you encounter this error and do not suspect a problem with your data, then you can eliminate this message in two ways.
- Change the level of the variable from Nominal to Interval in
the data source.
Add the following line of code in the Project Start Code:
%let EM_TRAIN_MAXLEVELS=n;
N equals the maximum number of levels that you want to allow.
Use whichever method you judge to be statistically appropriate for your analysis.
