1/* Data Envelopment Analysis (DEA)
2 *
3 * DEA quantifies the relative efficiency of decision making units (DMUs) by
4 * finding the efficient frontier in multiple input multiple output data.  The
5 * inputs are resources (eg. number of employees, available machines, ...),
6 * the outputs are productive outputs (eg. contracts made, total sales, ...).
7 * The method is non-parametric.  More details are available in the paper
8 * below.
9 *
10 * Models according to: Seiford, Threall, "Recent developments in DEA", 1990.
11 *
12 * Implementation: Sebastian Nowozin <nowozin@gmail.com>
