The investigation of samples containing many species: II. Sample comparison
1971
BULLOCK, J. A.
A comparison is made between a number of indices of similarity fer describing the similarities between multiple species samples, namely K, I, (1 - z), (x2/AT)1/2, r and a weighted similarity coefficient under various transformations. After discussing theoretical aspects of the indices, they are tested on two sets of data obtained by mist-netting birds. The resulting matrices are sorted by a simple nearest-neighbour agglomerative technique and later by principal component analysis. It is concluded that the V index, which is Kendall's rank correlation coefficient (Kendall, 1955), provides the most meaningful segregation, particularly under principal component analysis. Problems of subjective interpretation are discussed.
