Directional instability in the eigenvectors of positive reciprocal matrices
H. A. Donegan, T. B. M. McMaster · Journal of Multi-Criteria Decision Analysis · 1999
This article addresses the issues of rank stability and ‘bilateral’ consistency that arise when a matrix-based decision analysis procedure is perceived as capable of yielding more than one weighting vector, for example, both a right and component-wise inverted left eigenvector. Simple directional constraints that characterize both of the above issues are presented. Copyright © 1999 John Wiley & Sons, Ltd.
