Hello all, Now, I have a dataset as follows: MTMSTSCOCUCOWCUW A01000000 B01000000 C11000000 D11100000 E10000000 F01000000 G10000000 H10000000 A/B/C......H are the code of fish species, M/TM/S.....CUM are the name of my sites, 0 means absence, and 1 means the species is present. According to these, how should I form the similarity matrix among those sites? And which kind of similarity index should I take ? Is the Bray-Crutis similarity index is ok for me ? Thanks very much for your suggestion and your time.
