efficiencies.dea_fuzzy {deaR}

Efficiencies

Description

Extract the scores (optimal objective values) of the evaluated DMUs from a fuzzy DEA solution. Note that these scores may not always be interpreted as efficiencies.

Usage

## S3 method for class 'dea_fuzzy'
efficiencies(x, ...)

Arguments

x

Object of class dea_fuzzy obtained with some of the fuzzy DEA modelfuzzy_* functions.

...

Other options (for compatibility).
