Summary: Let \(X\) be a random variable with distribution function \(F\), the Pareto distribution. Eigendecomposition of the kernel \(F(s)\wedge F(t)-F(s)F(t)\) allows us to expand \(X\) as a series of principal components. The expansion of \(X\) for the general Pareto distribution can be expressed using the cylinder function, but may not be straightforward. We find the complete solution for a particular Pareto distribution, which can be expressed in terms of Bessel and trigonometric functions. A comparison with the exponential distribution is performed.
