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