abstract: Nonparametric efficiency measurement by data envelopment analysis. Provides
  radial (Charnes-Cooper-Rhodes and Banker-Charnes-Cooper) technical efficiency under
  constant, variable, non-increasing and non-decreasing returns to scale, the slacks-based
  measure of Tone (2001), the additive model of Charnes and others (1985), and the
  directional distance function of Chambers, Chung and Fare (1996), all through one
  interface and one result object. Efficiency estimates are accompanied by peers,
  slacks, returns-to-scale classification, scale efficiency and the optimal multipliers,
  and by bias-corrected estimates and confidence intervals from the smoothed homogeneous
  bootstrap of Simar and Wilson (1998), which also supplies a test of constant returns
  to scale for the sample as a whole (Simar and Wilson, 2002). Where prices are known,
  cost, revenue and Nerlovian profit efficiency separate the technical component from
  the allocative one; where they are not, cross-efficiency with the secondary goals
  of Doyle and Green (1994) ranks units that a self-appraisal leaves tied. This package
  succeeds the archived 'DEA' package of Diaz-Martinez and Fernandez-Menendez (2008).
