Q2 Text Exercises – Applied

8. In Section 10.2.3, a formula for calculating PVE was given in Equation 10.8

On the USArrests data, calculate PVE in two ways:

(a) redo as was done in Section 10.2.3.

(b) By applying Equation 10.8 directly. Then, use those loadings in Equation 10.8 to obtain the PVE. These two approaches should give the same results.
