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.
Logical. If it is TRUE
, it returns the linear problems
(objective function and constraints) of stage 1.
