Hello everyone,
We are experiencing some sporadic issues in running the LOGISTIC_REG function in Vertica 9.
In some cases, when executing the command:
SELECT LOGISTIC_REG ('model_oversampling_1', 'bank_oversampling_1', 'fraud', 'step, age, gender, amount' );
It gives this error:
ERROR 8306: Problem in creating model [model_oversampling_1].
Detail: A problem during the execution of writeModel.
Detail: Value exceeds range of type numeric(18,0)
It is not consistent, as it appears on a random basis and not always on the same logistic regression classifier present in the script. Also, trying with a BFGS optimiser does not seem to make a difference.
Do you have any ideas of what this might be? Should it be linked to memory limitations on the machine or could it be a bug on the LOGISTIC_REG function?
The issue didn't seem to be present in Vertica 8 but I'm not fully sure that this would never happen as it appears randomly.
Thank you very much!
Silvio
