transformation of Bray-Curtis in Euclidean
Yes, it is possible, and always has been when I have checked (which is not a proof). You can check this by seeing that it has no negative eigenvalues in principal coordinates analysis (apart from occasional negative almost-zero). Legendre & Legendre book discuss this. Cheers, Jari Oksanen
