With principal component analysis, we transform a random vector Z with correlated components Zi into a random vector D with uncorrelated components Di. Principal component analysis can be performed on any random vector Z whose second moments exist, but it is most useful with. Understanding the varability allows for creation of stressed interest rate term structures that can be applied as part of a risk management program wherever the.
