Perform these tasks in SAS Enterprise Miner:
* Continue to use the same diagram. Define and create the data set CREDIT_SCORE for scoring. The variables (their roles and measurement levels) in the CREDIT_SCORE data should be set as identical to those in the CREDIT dat a. The only exception is that the scoring data does not have a TARGET variable.
* Find the best model out of Decision Tree, Decision Tree (3-way), Regression, and Neural Network as defined by each of the four model's overall performance in the validation data measured by average squared error. Now, use this best model to score the CREDIT_SCORE data.
CREDIT SCORE:

The distribution of the predicted probabilities of TARGET=0 in the scoring data is approximately which of the following?
Response:

• A.bimodal
• B.left skewed
• C.right skewed
• D.normal

How many hidden layers are generally needed in an MLP-based neural network to capture a discontinuous relationship between inputs and target?
Response:

• A.no hidden layer, direct connection between inputs and output is preferred
• B.three or more hidden layers
• C.two hidden layers
• D.one hidden layer

You are building a model to identify fraud. Your model will produce predictions that can be interpreted as the probability of fraud. You will pass on the top 100 scoring cases to management for investigation. Assume that you have sufficient data to hold out a validation and test data set for model evaluation.
Which selection would represent a reasonable ordering of fit statistics (best to worst) for this situation?
Select one:
Response:

• A.ASE, Lift for the top 10%, ROC index
• B.R-square, AIC, K-S statistic
• C.ROC index, ASE, misclassification rate
• D.Misclassification rate, ROC index, ASE

What is the kurtosis value for the variable TLDel60Cnt24?
Response:

• A.less than 10
• B.between 10 and 13.99
• C.between 14 and 16.99
• D.17 or higher

Refer to the exhibit:

The SAS data set retail contains information on the count of retail store sales based on the following item types: bargain, essential, gourmet, and health. Based on the results from the Cluster Profile node, which statement is true?
Select one:
Response:

• A.The overall distribution of essential item sales is approximately normal and Segment 1 contains stores selling fewer than average essential items.
• B.The overall distribution of essential item sales is right skewed and Segment 4 contains stores selling higher than average essential items.
• C.The overall distribution of bargain item sales is left-skewed and Segment 4 contains stores selling fewer than average bargain items.
• D.The overall distribution of bargain item sales is approximately normal and Segment 1 contains stores selling fewer than average bargain items.
