Question 3 0.5 pts A non-parametric method generally performs well when the relationship between the response and the predictors is complex and the sample size is large. O True O False Question 4 0.5 pts As the flexibility of a statistical learning method increases, the method becomes more sensitive to the changes in the training set. O True O False Question 5 0.5 pts In a multiple regression model, if two predictors are highly correlated, the interaction between the two predictors tends to have a significant relationship with the response. O True O False Question 6 0.5 pts The larger the area under the ROC curve of a classification model, the larger the overall error rate of the model. True False Question 7 0.5 pts QDA is expected to result in less bias than LDA. True False Question 8 0.5 pts If the Bayes decision boundary is linear, LDA is expected to perform better on the training set than QDA. O True O False
