GUILDS                  Package implementing the Guilds sampling
                        formula for the Neutral Theory of Biodiversity
expected.SAD            Calculate the expected species abundance
                        distribution of the standard neutral model,
                        given theta, m and J
expected.SAD.Guilds     Estimate the expected species abundance
                        distribution of both guilds using the guilds
                        model, provided theta, alpha_x, alpha_y and J.
expected.SAD.Guilds.Conditional
                        Estimate the expected species abundance
                        distribution of both guilds using the guilds
                        model, provided theta, alpha_x, alpha_y,
                        conditional on the size of guild X, Jx and the
                        size of guild Y, Jy.
generate.ESF            Generate community data under the standard
                        neutral model of biodiversity, using the urn
                        scheme as described in Etienne 2005
generate.Guilds         Generate Artificial data under the GUILDS model
generate.Guilds.Cond    Generate Artificial data under the GUILDS
                        model, conditioned on Guild size
logLikelihood.ESF       Likelihood of the Etienne sampling formula
logLikelihood.Guilds    Likelihood of the Guilds sampling formula
logLikelihood.Guilds.Conditional

                        conditional on guild size
maxLikelihood.ESF       Maximization of the loglikelihood given the
                        standard Neutral Model, using the Etienne
                        Sampling Formula
maxLikelihood.Guilds    Maximization of the loglikelihood under the
                        Guilds Model.
maxLikelihood.Guilds.Conditional
