Description: 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).  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).
