The number of hidden layers in this Neural Network model is which of the following?
Response:

• A.1
• B.4 or more
• C.2
• D.3

Perform this task using SAS Enterprise Miner:
Continue to use the same diagram. Use an Ensemble node (configure using default options) in SAS Enterprise Miner to combine all four models.
Compare the performance of the ensemble and the four models using average squared error in the validation data. Which is the best model in this comparison?
Response:

• A.Decision Tree
• B.Ensemble
• C.Regression
• D.Neural Network

In SAS Enterprise Miner's Decision Tree node, which of the following types of target variable can be used?
Response:

• A.nominal with any number of categories
• B.all of the above
• C.interval
• D.binary

The number of neurons in this Neural Network model is which of the following:
Response:

• A.1
• B.4 or more
• C.2
• D.3

Perform these tasks in SAS Enterprise Miner:
- Use the Regression node to build another regression model with TARGET as the dependent variable and all other input variables as independent variables (main effects only).
- Configure the regression model to use Stepwise for Selection Model and Validation Error for Selection Criteri a. Do not change any other property for the regression model.
Consider the variable TLCnt03 in the selected model. Based on the model results, changing this variable by 1 unit will result in which of the following?
Response:

• A.change of odds for TARGET=1 by a factor 0.3457
• B.reduction of odds for TARGET=1 by 0.3457
• C.change of odds for TARGET=1 by a factor 0.708
• D.reduction of odds for TARGET=1 by 0.708
