The method is based on two scalar measures. The first is the relative frequency with which an observation appears in the construction of the frontier when testing the efficiency of other observations, and the second is the cumulative weight of an observation in the construction of the frontier. We provide a link to computer programming code for implementing the procedure.text/plainen-USIn CopyrightEconomic analysesFarm/Enterprise ScaleAbstractCopyright 2008 Taylor and Francis Grouphttps://doi.org/10.1080/13504850701765119
