This page is inconsistent with Simpson's diversity index, but this one is correct. Perhaps the other page should be deleted/merged? 128.42.145.156 (talk) 06:11, 10 November 2009 (UTC)

"Diversity of population" should be "diversity of community" since a population refers to one species - therefore, a measure of species richness cannot be applied to a population and instead must be applied to a community of species. 82.19.72.160 (talk) 17:08, 7 January 2010 (UTC)

Introduction[edit]

"A diversity index is a quantitative measure that increases when the number of types into which a set of entities has been classified increases, and obtains its maximum value for a given number of types when all types are represented by the same number of entities"

errr.. what? i think a simpler introduction is needed. --128.250.5.249 (talk) 07:48, 21 August 2012 (UTC)

Definition Shannon-Index[edit]

I think the definition is wrong, in my opinion it should be "ln" instead of "log". Maybe someone could check? --93.133.255.155 (talk) 16:54, 10 December 2012 (UTC)

True diversity (The effective number of types)[edit]

Why does the definition of qD have the term p_i*p_i^(q-1), when this is simply equal to p_i^q? It seems these two p's may be slightly different, however this is not clear in the text. — Preceding unsigned comment added by Bbeckerman (talkcontribs) 21:51, 23 September 2013 (UTC)
