...)A list of class dea with the results for the evaluated DMUs (DMU component),
along with any other necessary information to replicate the results, such as
the name of the model and parameters orientation, rts,
dmu_eval and dmu_ref.
A deadata object, including n DMUs, m inputs and s outputs.
A numeric vector containing which DMUs have to be evaluated.
If NULL (default), all DMUs are considered.
A numeric vector containing which DMUs are the evaluation reference set.
If NULL (default), all DMUs are considered.
A string, equal to "no" (non-oriented), "io" (input oriented), or "oo" (output oriented).
Logical. If it is TRUE, it applies the IRDM (inverse range
directional model).
Logical. If it is TRUE, it computes the max slack solution.
A value, vector of length m, or matrix m x
ne (where ne is the length of dmu_eval) with the weights
of the input slacks for the max slack solution.
A value, vector of length s, or matrix s x
ne (where ne is the length of dmu_eval) with the weights
of the output slacks for the max slack solution.
Logical. If it is TRUE, it computes targets of the
max slack solution. We note that we call "targets" to the "efficient projections"
in the strongly efficient frontier.
Logical. If it is TRUE, it returns the linear problems
(objective function and constraints) of stage 1.
