qDEA 1.0.0

Initial CRAN Release

• First public release of qDEA package
• Implements quantile Data Envelopment Analysis methods
• Main function qDEA() for efficiency analysis with multiple orientations
• Support for various returns to scale specifications (CRS, VRS, DRS, IRS)
• Bootstrap bias correction procedures
• Subsample size selection following Simar and Wilson (2011)
• Helper functions for DEA model building and LP solving
• Four example datasets from Cooper, Seiford, and Tone (2006)
• Integration with highs solver for linear programming

Key Features
