Compute efficiencies for (standard) DEA model
For the given orientation, input, output and weights compute DMU's efficiencies
eff_dea(input, output, orientation, ux, vy)
input: A matrix or a data frame containing the inputs of the units to be evaluated, with one row for each DMU and one column for each input.output: A matrix or a data frame containing the outputs of the units to be evaluated, with one row for each DMU and one column for each output.orientation: Use "input" for input orientation or "output" for output orientation in DEA model. The default is "input".eff
Unlike the dea function, this function expects input and output to be arrays or data.frames, not vectors.
Note: As this function is mainly for internal use, to avoid unnecessary overload, it does not do an extensive check of the input parameters. Use the higher level dea function instead.
