The following list has statements about the classifiers. In the list, there is a single incorrect statement. Please identify the incorrect
statement.
Hint 1: recall that a classifier dominates another if both performance measures are better.
Hint 2: to help you visualize and compare classifiers, you may want to plot the classifier data in a ROC graph (which will not be
submitted).
Select one:
Qa.

This data set will be analysed after centering all columns (not scaling). In what follows, the centered data columns are referred to as
X and Y. Using these centered columns, we have the following quantities: XTX = 24/11 = 2.1818; XTY = 13/11 =
and YTY = 24/11 = 2.1818.

0.56, compute and write in the provided space the ridge estimate ẞ (0.56). Use decimal numbers, not fractions.
Q2 Using the ridge estimate ẞ (0.56) you just computed, determine the percentage of shrinkage achieved with respect to the
squared L2 norm. That is, compute the shrinkage using || (0.56)||||||with the OLS estimate. In the provided space, write
the shrinkage as percentage between 0 and 100 with decimal values.
