Fig 3. Fittings to the step length distribution for 6 Amazonian farmers searching for Brazilian nuts.
Rank frequency plots of the step lengths are shown (o) together with fits to power-law (red-lines), exponential (blue lines) and bi-exponentials (green lines). The Akaike weights, wp and wbi, for the power-law and bi-exponential fits are shown together with the maximum likelihood estimates for the power-law (Lévy) exponents, μ. The numbers of steps are 368, 317, 214, 241, 444 and 871.
