Neutral Biodiversity Theory distribution by Volkov emph{et al.
Density, distribution function, quantile function and random generation for species abundances distribution in a neutral community with immigration as deduced by Volkov et al. (2003).
This function works almost exactly as bbmle's summary.mle2, but it includes a "fixed parameters" line for models with fixed parameters, such as fitls or fitvolkov.
Plots empirical percentiles vs corresponding theoretical values expected by a model for species abundances (SAD) or a model for species abundance ranks (RAD).
Creates an object of octav-class with the frequencies of species in octaves of abundances predicted by a species abundance distribution or by a rank-abundance distribution.
Given a likelihood profile of a model (object of the class profile.mle or profile.mle2), the function plotprofmle plots the relative log-likelihood profiles and the plausibility intervals for each one of the (or selected ones) parameters of a model. These same plausibility regions might be returned by likelregions.
