Le title statement pour le titre est universelle, n'import la proc. L'option height commande la taille. Essaie avec "title height=20pt". L'exemple suivant utilisse le title statement directement avant la proc. C'est pareil pour proc gplot, proc sgplot, et quelques autres proc statistiques. Le titre est partie de l'ODS, pas exactement partie de la proc, mais les resultats de la proc montrent le titre. Je recommends title statement directement avant la proc pour le graphiques, pas dans la proc greplay. Mais ca marche aussi pareil pour la proc greplay. exemple title2 j=center color=red underlin=1   height=28pt "1"   height=24pt "9"   height=20pt "9"   height=16pt "6"; a lire: SAS(R) 9.2 Language Reference: Title statement merci, Miguel ...

Hi Karen, The ASSOC procedure runs behind the scenes of the Association node in SAS Enterprise Miner. The goal is to find rules for items that appear together in a transaction data set, as well as calculating the support and confidence for such rules. Here a screenshot of the results of Association node items link graph and support vs confidence plots. association_analysis_screenshot.png The easiest is to use the Association node in SAS Enterprise Miner. However, if you want to understand the technical side of Association node, take a look at this document. It describes how how PROC DMDB, PROC ASSOC, and PROC RULEGEN work together. http://support.sas.com/documentation/onlinedoc/miner/em43/rulegen.pdf Examples of SAS Enterprise Miner Association node Data Mining Using SAS® Enterprise Miner : A Case Study Approach, Second Edition - Chapter 5 Shopping for Voters: Using Association Rules to Discover Relationships in Election Survey I hope this helps!

By default the Ensemble node averages the predicted probabilities of your models. If you have a class target, you can specify Posterior Probability as Voting. Voting can be done in two ways: -average. The posterior probabilities of an event are averaged, and the event with higher average predicted probabilities is selected. -proportion. The proportion of predicted events is selected. Priority is given to the descending level. To answer your specific question, consider this example. For a given observation these are the posterior probabilities of four models for the levels Yes and No: Model Prob of Yes Prob of No Model 1 0.6 0.4 Model 2 0.7 0.3 Model 3 0.1 0.9 Model 4 0.15 0.85 Ensemble Voting by Average The average posterior probabilities are 0.3875 for Yes and 0.6125 for No. For this example, the predicted level would be No. Ensemble Voting by Proportion This ensemble assigns a predicted probability of 0.5 since two out of four models predict each level. In this tie case, the event Yes is given priority because targets are formatted with descending order by default in Enterprise Miner. I hope this helps! Miguel ... View more
