Abstract:
The logarithm of the determinant of a contingency table allows evolutionary information to be recovered from data generated under very general stochastic models. The variance of the estimate of the dissimilarity between taxa is generally estimated with the help of resampling methods. We show that this technique leads to biased estimates, and we derive exact formula. Practical implications are considered.
