To be Levy, or not to be: that is the question

Last month, Science published this paper: “Our results question the strength of the empirical evidence for biological Levy flights.”

People have been developing theoretical models assuming Levy flights for twenty years now.

But, no worries, seems to suggest this paper currently discussed at HotNets: “We conduct a statistical study of human mobility… Our data reveals statistical features similar to those in what physicists have long called Levy random walks (or Levy walks).”

Physicists have long called them so, but they have apparently just stopped. How much more confusing can it get?

P.S. In the Science paper, consider also the allure of Box 1 exotically titled “When is a power law not a power law?”
