Predictive Modeling using SAS Enterprise Miner - Decision Trees

Project Screenshots

The following are screenshots of the steps that are performed on the dataset :

• How many leaves are in the optimal tree?

• Which variable was used for the first split? What were the competing splits for this firstsplit?

• Add a second Decision Tree node to the diagram and connect it to the Data Partition node.

• How many leaves are in the optimal tree?

The three way split has 33 leaves.

Decision Tree

• Based on the average square error, which of the decision tree models appears to be better?

From the above outputs Decision tree 2 is a better model, as with three-way splits has the lower validation average square error.
