## Free SAS A00-240 Exam Actual Questions

### The questions for A00-240 were last updated On Aug. 04, 2022

Question #1

Refer to the exhibit:

Which SAS program produced the graph?

Question #2

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?

Question #3

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.

Question #4

Refer to the exhibit:

On the Gains Chart, what is the correct interpretation of the horizontal reference line?

Question #5

Refer to the confusion matrix:

Calculate the accuracy and error rate (0 - negative outcome, 1 - positive outcome)
