Data envelopment analysis was introduced as a nonparametric linear programming estimator to estimate the production frontier and technical efficiency of observed production units. Allowing multiple inputs and multiple outputs, the approach can be considered a nonparametric quantile regression...

Data envelopment analysis (DEA) is used as a tool for technical efficiency evaluation of decision making units. These units are compared with each other. The comparison is based on the size of inputs and outputs. In case of an inefficient unit, there is a possible of ordaining necessary changes...
