Species associations through Kendall’s coefficient of concordance
Pierre LegendreNovember 2004

This program computes a test of the concordance among several judges (which may be species in ecology) using Kendall’s W statistic. The search for species associations is one of the classical problems of community ecology. The program also tests the contributions of individual judges (species) to the overall W statistic, as described in Legendre (2005). The global and a posteriori tests are conducted by permutation.
