[edit] Jensen

What's with this application of Jensen inequality? That is just a generalization of concavity from sums to integrals. Since here we only use a 2term sum exactly as per the definition of concavity, there is absolutely no need to include Jensen in the proof. MarSch 14:21, 14 Mar 2005 (UTC)

You're right; I was very hasty. Although it is indeed a special case of J's inequality, it's a vacuous one. Michael Hardy 23:08, 14 Mar 2005 (UTC)
