SASInstitute SAS Predictive Modeling Using SAS Enterprise Miner 14 認定 A00-255 試験問題：

問題 #1

Perform these tasks in SAS Enterprise Miner:
- Add a Decision Tree node after the Impute node with TARGET as the dependent variable and all other input variables as independent variables (main effects only). Configure the decision tree to use 1 for Number of Surrogate Rules and Largest for Method in Subtree. Do not change any other property of the Decision Tree node.
- Add another Neural Network node after the decision tree with TARGET as the dependent variable and all other input variables as independent variables (main effects only). Configure the Neural Network model to use Average Error for Model Selection Criterion. Do not change any other property for the Neural Network node. Run the process flow.
Which of the following variables was used in the decision tree model?
Response:

A. IMP_TLSatCnt
B. TLDel90Cnt24
C. InqFinanceCnt24.
D. TLDel3060Cnt24

問題 #2

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.
Which of the following variable(s) is (are) statistically significant at the 5% level in the selected model?
Response:

A. TLTimeFirst
B. all of the above
C. IMP_TLOpen24Pct
D. TLDel3060Cnt24

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

問題 #4

1. Create a project named Insurance, with a diagram named Explore.
2. Create the data source, DEVELOP, in SAS Enterprise Miner. DEVELOP is in the directory c:\workshop\Practice.
3. Set the role of all variables to Input, with the exception of the Target variable, Ins (1= has insurance, 0= does not have insurance).
4. Set the measurement level for the Target variable, Ins, to Binary.
5. Ensure that Branch and Res are the only variables with the measurement level of Nominal.
6. All other variables should be set to Interval or Binary.
7. Make sure that the default sampling method is random and that the seed is 12345.
What is the mean credit card balance (CCBal) of the customers with a variable annuity?
Response:

A. $9,586.55
B. $0.00
C. $11,142.45
D. $8,711.65

問題 #5

Suppose your input variables have missing values. Before running a decision tree with these input variables, you should do which of the following?
Response:

A. impute all missing values using the Tree method
B. impute only interval variables using the Tree method but do not impute the class variables
C. not impute any missing values because trees can handle them.
D. impute only class variables using the Tree method but do not impute the interval variables
