質問 1：
What percentage of observations in the test data has TARGET=1?
Response:
A. 16.5924
B. 16.6627
C. 16.8874
D. 83.3333
正解：C
質問 2：
Perform these tasks in SAS Enterprise Miner:
Add a Decision Tree node, as shown below. (Make sure you use only default options in the Decision Tree node.)
Run the Decision Tree node.
Suppose that the data has been oversampled and the probability that TARGET=1 is 0.10 in the population. Incorporate the above scenario and run the Decision Tree node again.
What is the misclassification rate in the validation data set?
Response:
A. 0.10
B. 0.157016
C. 0.154788
D. 0.162252
正解：B
質問 3：
Perform these tasks in SAS Enterprise Miner:
* Add a Decision Tree node, as shown below. (Make sure you use only default options in the Decision Tree node.)
* Run the Decision Tree node.
In the training data set, consider only those observations for which the actual value of the target variable equals 1, TARGET=1. What percentage of these observations is being correctly predicted by the decision tree?
Response:
A. 14.6216
B. 66.6667
C. 80.3571
D. 15
正解：D
質問 4：
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
正解：C
質問 5：
What is the kurtosis value for the variable TLDel60Cnt24?
Response:
A. between 14 and 16.99
B. between 10 and 13.99
C. 17 or higher
D. less than 10
正解：A
質問 6：
Refer to the following profit matrix and confusion matrix for a campaign soliciting product purchases. The predicted variable is a binary outcome.
Based on the above tables, what is the average profit? You may use a calculator for this question. On the certification exam, an on-screen calculator is provided for you.
