Solving degeneracy and stability in nonmetric unfolding

► We identify and resolve degeneracy issues in nonmetric unfolding. ► We formulate stability measures for nonmetric unfolding solutions. ► We use the stability measures to obtain stable nondegenerate nonmetric unfolding solutions. ► We introduce methods for visualizing stability estimates in nonmetric unfolding. ► We illustrate the power of our methodology by applying it to three data sets.
