eff_dmus function

Efficient DMUs.

Returns the efficient DMUs evaluated in a dea class object.

eff_dmus(deasol, tol = 1e-04)

Arguments

• deasol: An object of class "dea" obtained by a DEA model function.
• tol: Numeric. Absolute tolerance for numeric comparisons in efficiency scores. By default, it is 1e-4.

Returns

A numeric vector containing which DMUs has been evaluated as efficient. This vector is empty if there is not any efficient DMU.

Note

If maxslack is FALSE, the slacks computed in the first stage are supposed to be the max slacks.

Examples

dataFortune <- make_deadata(Fortune500,
                            ni = 3,
                            no = 2)
ccrFortune <- model_basic(dataFortune)
eff_dmus(ccrFortune)
