title: 'psdea: Data Envelopment Analysis with User-Defined and Learned Reference Sets'
version: 1.0.0
abstract: Slacks-based data envelopment analysis for panel data in which the reference
  set is an explicit argument. A user-supplied weight matrix, or a matrix learned
  from the data by penalised non-negative reconstruction, selects the units that may
  enter each decision-making unit's frontier. The package reports the unrestricted
  and the restricted score, the ratio of the two and an exact decomposition of the
  shortfall into the part the restricted technology can remove and the part it cannot.
  Moran's I and local indicators of spatial association are provided as diagnostics.
  All linear programs are solved by a two-phase simplex with Bland's rule implemented
  in R, so the package needs no compiler.
