Inference on functional biodiversity tools

Biodiversity profiles can be analysed in a functional framework because they are expressed as functions of the unknown abundance vector. This paper aims to construct simultaneous confidence bands for the β-diversity profile and for its functional mean. Using a suitable sampling design, inference is developed assuming an asymptotic specific distribution of the profile estimator. The use of any probability distribution is hazardous because ecologists generally deals with small sample sizes. For this reason we propose simultaneous confidence bands adopting a non-parametric bootstrap
