Talk:Sørensen similarity index

From Wikipedia, the free encyclopedia

Hi folks,

I don't agree with your formula and deleted the "2" on top!!

Greetings from Germany (where the "Sørensen similarity index" hopefully isn't different from yours)

Hello everyone

I brought back the "2" in the upper term as this is absolutely correct. (e.g. Anne E. Magurran, Measuring Biological Diversity, p. 173) Greetings from Germany, too.
