A00-255 無料問題集「SASInstitute SAS Predictive Modeling Using SAS Enterprise Miner 14」

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.
What percentage of all observations is being correctly predicted in the test data set by the decision tree?
Response:

Which of the following is not true about results produced by the Regression node?
Response:

Look over the output from the Neural Network model. Which of the following statement(s) is (are) true?
Response:

What percentage of observations in the test data has TARGET=1?
Response:

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.
For the validation data, in what range does cumulative percent captured response at the 60th percentile lie?
Response:

Which of the following is not a good reason to"regularize" input distributions using a simple transformation?
Response:

Transformation of input variables to make their distributions more symmetric will likely have what impact in a logistic regression?
Select one:
Response:

If the bank wanted to select the best model based on which model achieves the highest lift for the third decile in the validation data, then which of the following is the best model?
Response:

Which method of input selection for regression analysis evaluates the statistical significance of all included inputs after each input is added?
Select one:
