Fig. 9: Three-dimensional sensitivity analysis of the evaluation results with respect to double parameters.
From: Regret cross-efficiency evaluation using attitudinal entropy approach
a represents the sensitivity analysis of the double parameters ς and λ, (b) shows the sensitivity analysis of the double parameters a/b and α, and (c) presents the sensitivity analysis for the double parameters α and δ. Each surface represents the efficiency of different DMUs as the two parameters vary. The different colors represent different DMUs, and the efficiency is plotted on the z-axis.
