+\subsection{Cauchy distribution}
+The \Index{Cauchy distribution}, also called the \Index{Lorentz distribution}, is a continuous distribution
+describing resonance behavior. It also describes the distribution of horizontal distances at
+which a line segment tilted at a random angle cuts the $x$-axis.
+
+The general Cauchy distribution and its cumulative distribution can be written as
+\begin{align}
+P(x) &= \frac{1}{\pi} \frac{b}{\left(x-m\right)^2+b^2}\\
+D(x) &= \frac12 +\frac{1}{\pi} \arctan\left(\frac{x-m}{b}\right)
+\end{align}
+
+where \Lkeyword{b} is the half width at half maximum and \Lkeyword{m} is the statistical median.

+\section{The Lorenz curve}
+
+The so-called \Index{Lorenz curve} is used in economics to describe inequality in
+wealth or size. The Lorenz curve is a function of the cumulative proportion of
+\textit{ordered individuals} mapped onto the corresponding cumulative proportion
+of their size. Given a sample of n ordered individuals with $x_i^{\prime}$ the size of
+individual $i$ and $x_1^{\prime}<x_2^{\prime}<\cdots<x_n^{\prime}$, then the sample Lorenz curve is
+the \textit{polygon} joining the points $(h/n,L_h/L_n)$, where $h=0, 1, 2,\ldots n, L_0=0$, and
+$L_h=sum_(i=1)^(h)x_i^{\prime}$.
