I just wondering this situation.
If i set the CREATE SAMPLES tools as 70%-30% (Estimation-Validation) for a workflow consists of LOGISTIC REGRESSION, it seem working nicely without any error.
But if i change the setting 34%-33%-33% (Estimation-Validation-Holdout), i got the error:
Anybody can can tell me why this happen?
And what is the solution on this?
Thank you in advance
It is possible that a field value is present in the evaluation data that isn't part of the training data. Your sample doesn't contain all of the field values.
TQ MarqueeCrew for quick response.
Actually it reading the same input file and should got the same field.
There is nothing change in the workflow except this.It should be any problem, am I right?
I think so
