Question #87
What is a benefit to performing data cleansing (imputation, transformations, etc.) on data after partitioning the data for honest assessment as opposed to performing the data cleansing prior to partitioning the data?
It makes inference on the model possible.
It is computationally easier and requires less time.
It omits the training (and test) data sets from the benefits of the cleansing methods.
It allows for the determination of the effectiveness of the cleansing method.
Answer: D Question #88
A researcher has several variables that could be possible predictors for the final model. There is interest in checking all 2-way interactions for possible entry to the model. The researcher has decided to use forward selection within PROC LOGISTIC. Fill in the missing code option that will ensure that all 2-way interactions will be considered for entry.
start = 5
include = 4
include = 5
start = 4
Answer: C Question #89
FILL BLANK -
Refer to the confusion matrix:
An analyst determines that loan defaults occur at the rate of 3% in the overall population. The above confusion matrix is from an oversampled test set (1 = default). What is the sensitivity adjusted for the population event probability?
Enter your answer in the space below. Round to three decimals (example: n.nnn).
Answer: 0.617
Question #90
Refer to the exhibit:
On the Gains Chart, what is the correct interpretation of the horizontal reference line?
the proportion of cases that cannot be classified
the probability of a false negative
the probability of a false positive
the prior event rate
Answer: B Question #91
Refer to the confusion matrix:
Calculate the accuracy and error rate (0 - negative outcome, 1 - positive outcome)
Accuracy = 58/102, Error Rate = 23/48
Accuracy = 83/102, Error Rate = 67/102
Accuracy = 25/150, Error Rate = 44/150
Accuracy = 83/150, Error Rate = 67/150
Answer: A Question #92
Which statistic is based on the maximum vertical distance between the primary event EDF and the secondary event EDF?
KS
SBC
Max EDF
Brier Score

Question #93 DRAG DROP -
Drag the adjustment formulas for oversamping from the left and place them into the correct location in the confusion matrix shown on the right. Select and Place:
Answer:
Question #94
An analyst knows that the categorical predictor, zip_code, is an important predictor of a binary target. However, zip_code has too many levels to be a feasible predictor in a model. The analyst uses PROC CLUSTER to implement Greenacre's method to reduce the number of categorical levels.
What is the correct application of Greenacre's method in this situation?
Clustering the levels using the target proportion for each zip_code as input.
Clustering the levels using the zip_code values as input.
Clustering the levels using the number of cases in each zip_code as input.
Clustering the levels using dummy coded zip_code levels as inputs.

What does the Pearson product moment correlation coefficient measure?
nonlinear and nonmonotonic association between two variables
linear and monotonic association between two variables
linear and nonmonotonic association between two variables
nonlinear and monotonic association between two variables

This question will ask you to provide a missing option. Given the following SAS program:
What option must be added to the program to obtain a data set containing Spearman statistics?
OUTCORR=estimates
OUTS=estimates
OUT=estimates
OUTPUT=estimates
Answer: D Question #98
This question will ask you to provide a missing option.

Question #99
After performing an ANOVA test, an analyst has determined that a significant effect exists due to income. The analyst wants to compare each Income to all others and wants to control for experimentwise error.
Which GLM procedure statement would provide the most appropriate output?
lsmeans Income / pdiff=control adjust=dunnett;
lsmeans Income / pdiff=control adjust=t;
lsmeans Income / pdiff=all adjust=tukey;
lsmeans Income / pdiff=all adjust=t;
