Questions with Complete Solutions.
PLS Regression?
Correct!
The choice of k depends on the application and can be chosen
by the cross validation
The choice of k should be as large as possible, say, k=p.
The choice of k should be a small number such as k=2,3 or 5.

Question 2 pts Mining
In the linear regression model
, the Laplace Prior on yields the estimator of the form
Correct!
LASSO
Ridge regression
None of the
above
Question 3 pts
What is the main difference between linear discriminant
analysis (LDA) and Logistic regression?
Correct!
Logistic regression is often more robust than LDA, since it does
not make any assumption on the marginal distribution of X.
