Description: R implementation of Quantile Data Envelopment Analysis.
        The package 'qDEA' allows a user specified proportion of
        observations to lie external to a given Decision Making Units's
        (DMU's)reference hyperplane. 'qDEA' can be used to detect and
        address influential outliers or to implement quantile
        benchmarking, as discussed in Atwood and Shaik (2020). Quantile
        benchmarking is accomplished by using heuristic procedures to
        find a DMU's closest input-output projection point in a
        specified direction while allowing a specified proportion of
        observations to lie external to the projected point's
        hyperplane. The 'qDEA' package accommodates standard (DEA) and
        quantile DEA estimation, returns to scale
        CRS(constant),VRS(variable),DRS(decreasing) or IRS(increasing),
        the use of directional vectors, bias correction through
        subsample bootstrapping and subsample size selection
        procedures. The user can also recover each DMU's reference DMUs
        and external DMUs if desired. The implemented procedures are
        based on discussions in: Atwood and Shaik (2020)
