Error proc treeboost measure=LIFT

[Amelie]

Bonjour à tous,

J'ai un message d'erreur étrange lorsque je souhaite lancer ma proc treeboost en précisant measure=LIFT

Message d'erreur : ERROR: Internal Error: ABNORMAL return ignored.

Voici mon code :

PROC TREEBOOST DATA=sasuser.train3 
LEAFSIZE=100
MAXBRANCH=3
ITERATIONS=50 
MINCATSIZE=15
SEED=05042017
SHRINKAGE=0.1
SPLITSIZE=100
TRAINPROPORTION=0.5
;
INPUT &VAR_FAI. / LEVEL=INTERVAL INTERVALDECIMALS=5 ORDER=DESCENDING;
INPUT &VARTEXT. / LEVEL=NOMINAL;
TARGET FLG_CHURN /LEVEL=BINARY;
IMPORTANCE OUTFIT=sasuser.BASE_VARS50;
SUBSERIES BEST;
ASSESS measure=LIFT proportion=0.20;
SAVE IMPORTANCE=sasuser.gbm01varimp50 MODEL=sasuser.gbm01modl50;
RUN;

Merci d'avance pour votre aide

The TREEBOOST procedure is a non-HP procedure used by the Gradient Boosting node in SAS Enterprise Miner and is available only to those who have SAS Enterprise Miner licensed.  Unfortunately, there is no support available for the direct use of these non-HP procedures since they were not intended to be used directly.   If you have SAS Enterprise Miner licensed, you can run the Gradient Boosting node to see how TREEBOOST is used. 

Having said that, the Gradient Boosting node examples I ran always showed

         proc arbor proc=treeboost data=dataset ....

so it might just be the way you are trying to use TREEBOOST.   

Hope this helps!

Doug

Hi Doug,

Thank you for your answer.

I forgave to precise this procedure it's totally OK if I don't precise "measure=LIFT" and the proportion.

That's why I don't understand why the measure option doen't run...
