reciprocal averaging An ordination method that combines gradient analysis and a system of successive approximation. Its chief merit lies in the clarity with which strong floristic gradients are displayed. For the non-mathematical ecologist the method is conceptually easier to follow and to calculate than the most widely used alternative multivariate evaluation scheme, principal components analysis.
