Spearman statistics in the CORR procedure are useful for screening for irrelevant variables by investigating the association between which function of the input variables?
A. Logit link (log (p/1-p))
B. Rank-ordered values of the variables
C. Weighted sum of chi-square statistics for 2x2 tables
D. Concordant and discordant pairs of ranked observations
正解：B
質問 2：

* One categorical predictor variable (c1 with 3 levels)
Which SAS program fits this model?
A. Option C
B. Option A
C. Option D
D. Option B
正解：C
質問 3：
A non-contributing predictor variable (Pr > |t| =0.658) is added to an existing multiple linear regression model.
What will be the result?
A. A decrease in R-Square
B. An increase in R-Square
C. A decrease in Mean Square Error
D. No change in R-Square
正解：B
質問 4：
Refer to the exhibit:
Based upon the comparative ROC plot for two competing models, which is the champion model and why?
A. Candidate 1, because it is closer to the diagonal reference curve
B. Candidate 2, because it shows less over fit than Candidate 1
C. Candidate 2, because the area under the curve is greater
D. Candidate 1, because the area outside the curve is greater
正解：C
質問 5：
Refer to the exhibit:
The box plot was used to analyze daily sales data following three different ad campaigns.
The business analyst concludes that one of the assumptions of ANOVA was violated.
Which assumption has been violated and why?
A. Normality, because the interquartile ranges are different in different ad campaigns.
B. Constant variance, because Prob > F < .0001.
C. Constant variance, because the interquartile ranges are different in different ad campaigns.
D. Normality, because Prob > F < .0001.
正解：C
