What is the mathematical model behind weighting?
The weight restriction model used in Frontier Analyst® is based on the use of proportions (Wong and Beasley 1990). These proportions determine how prominently a particular (input or output) variable must feature in the efficiency ratings of the units. Consider a DEA analysis that includes the output variable Profit . If the user specifies that the weight assigned to profit must be between 0.3 and 0.8, then she is stating that Profit must contribute at least 0.3 and at most 0.8 of the total weighted output used to determine a unit s efficiency.
